mon08 cyclone user manual 3 p&e microcomputer systems, inc. mon08 cyclone 1 introduction the mon08 cyclone is designed to control the motorola 68hc908 targets in-circuit via the monitor rom (mon08 port). the cyclone acts as a debugging/programming tool. it communicates with pc through a standard rs-232 port. in addition, the mon08 cyclone can function as a stand- alone programmer. once configured properly, it can program target devices independent of a pc. some of the features that make the mon08 cyclone versatile are: a. software configurable port pin settings for monitor rom entrance. b. works with 3.3v and 5v targets with internal bus frequency ranges from 1mhz to 8mhz. c. automatically detects target internal bus frequency and sets communications baud rate. d. automatically cycles target power using electromechanical relays during security protocol. e. provides 5v 9.8304 mhz oscillator signal to overdrive target crystal and rc clock circuitry. 2 mon08 cyclone hardware 2.1 mon08 cyclone power supply the mon08 cyclone requires a regulated 5v dc center positive power supply with 2.5/5.5mm female plug. the mon08 cyclone derives its power from the power jack located beside the db9 female connector. 2.2 rs232 communication the mon08 cyclone provides a db9 female connector to communicate with a host computer through the rs232 communication (57600 baud, 8 data bits, no parity, 1 stop bit).
4 mon08 cyclone user manual p&e microcomputer systems, inc. mon08 cyclone 2.3 electromechanical relays inside the mon08 cyclone, two electromechanical relays are used to cycle target power. the specifications of the relays are as following: maximum switched power: 30w or 125 va maximum switched current: 1a maximum switched voltage: 150vdc or 300vac ul rating: 1a at 30 vdc 1a at 125 vac 2.4 power connectors the mon08 cyclone provides a target power supply input jack and a target power supply output jack with 2.5 mm pin diameter. the power jacks are connected or disconnected by two electromechanical relays. when connected, the center pin of the target power supply input jack is connected to the center pin of the target power supply output jack. figure 2-1: power connector locations 2.5 jumper settings the mon08 cyclone provides five jumpers to make the power management more convenient. the five jumpers are specified as follows, beginning with the jumper next to the target power supply input jack. jumper function 1 target voltage = 5 volts 2 target voltage = 3.3 volts 3 power in vcc connected to cyclone generated power (5v or 3.3v) 4 power in/out gnd connected to cyclone gnd
mon08 cyclone user manual 5 p&e microcomputer systems, inc. mon08 cyclone mon08 cyclone 5 power out vcc connected to mon08 connector pin 15 jumper 1 and jumper 2 notifies the mon08 cyclone of the target mcu voltage. either jumper 1 or jumper 2 must be shorted, but not both. jumper 3 and jumper 4 are provided to enable the target board to draw power from the cyclone so that the power in jack is not needed. in this case, the target power has to be either dc 5v (jumper 1) or 3.3v (jumper 2). jumper 5 connects pin 15 of the mon08 connector with the center pin of the target power supply output jack. if jumper 4 and jumper 5 are shorted the target may obtain power through the ribbon cable and the target power supply jack is not needed. 2.6 optional oscillator the mon08 cyclone provides a 5v 9.8304 mhz oscillator clock signal to pin 13 of the mon08 connector. if the target is a 5v system, the user may use this clock signal to overdrive the target rc or crystal circuitry. if this signal is not used, just leave pin 13 of the target mon08 header unconnected. please note that if the target already uses an oscillator as its clock, the cyclone will not be able to overdrive it. the clock should have sufficient drive to be used with a target system even if the target system has an rc circuit or crystal connected.
6 mon08 cyclone user manual p&e microcomputer systems, inc. mon08 cyclone 2.7 target mon08 connector the mon08 cyclone provides a standard 16-position 0.100-inch pitch dual row 0.025-inch square header. the mechanical drawing is shown in figure 2- 2 . figure 2-2: 16-pin header mechanical drawing the mon08 connector adopts the standard pin-out from mon08 debugging (as used on different ics boards) with some modifications. the general pin-out is as follows: pin 1 - nc gnd - pin 2 pin 3 - nc rst - pin 4 pin 5 - nc irq - pin 6 pin 7 - nc mon4 - pin 8 pin 9 - nc mon5 - pin10 pin11 - nc mon6 - pin12 pin13 - osc mon7 - pin14 pin15 - vo u t mo n 8 - pin16

36 mon08 cyclone user manual p&e microcomputer systems, inc. mon08 cyclone the cyclone for stand alone programming. 5.1 command line parameters there are two command line parameters of interest. one is the v parameter, which will ignore the object file s-record address range check. the other is the ? parameter, which allows the cyclone configuration status window stay after its operation. this enables you to take a look at the procedure and see that everything is ok, or, for you to find out at which step it is experiencing difficulties. 5.2 port pin settings the following sections of the configuration dialog concern port pin settings. figure 5-2: port pin settings - 68hc908ab family 5.2.1 target type the user should choose the target type that best describes the target mcu to be programmed. for example, choose ab for a 68hc908ab32 device, and choose gr16 for a 68hc908gr16 device. the mon08 header connections are shown on the right hand side for user reference. please refer to chapter 4 for detailed information. 5.2.2 clock selection the user may choose to use the cyclone clock to overdrive the target rc or crystal circuitry. in this case the 9.8304 mhz oscillator signal of the cyclone is connected to the target mon08 header pin 13 through the ribbon cable. the user should connect the target mcu osc1 pin to pin 13 of the mon08 header. if the user chooses to use the target clock, nothing is needed for the pin 13 of the target mon08 header. the 9.8304 mhz oscillator signal of the cyclone will be disabled.
mon08 cyclone user manual 37 p&e microcomputer systems, inc. mon08 cyclone mon08 cyclone 5.2.3 clock division the user may freely choose the clock division (if the target supports) as long as the target bus frequency stays within specification. if the port pin that determines the clock division is not connected to the target mon08 header, the user can safely ignore this selection. typically the clock division does not affect the communications between the mon08 cyclone and the target. normally a smaller clock division leads to faster target bus frequencies, and faster communications between the mon08 cyclone and the target, which in turn leads to a shorter programming time. 5.3 baud rate and security settings figure 5-3: baud rate and security settings dialog section this configuration field provides faster monitor rom entrance for known baud rate and security bytes. if the use specified baud rate and security bytes checkbox is checked, the baud rate and security bytes that are specified in this field are tried first when the cyclone contacts the target. if the target enters the monitor mode successfully, the cyclone will execute the instructed programming operations immediately. if use specified baud rate and security is not checked, or if the target fails to enter the monitor mode using the specified baud rate and security bytes, the cyclone will automatically detect the communications baud rate, ignore the security, enter the monitor mode, erase the target device, power cycle the target, and re-enter the monitor mode using blank security bytes. 5.4 target power down/up delay in milliseconds figure 5-4: target power down/up delay dialog section the user needs to take into account the power discharge time for the power down delay. the reset driver delays, power stabilization time, and the target clock stabilization time should be considered for the power up delay.

54 mon08 cyclone user manual p&e microcomputer systems, inc. mon08 cyclone the device type selection box allows the user to specify what type of hc08 they are communicating with. the dialog will then display the appropriate pinout to be implemented on the mon08 connector, so that the p&e interface can talk to it properly. the values given (1 or 0) are for informational purposes only and are driven by the p&e interface. device power figure 6-21: device power dialog the device power selection allows the user to specify whether the target is 2, 3, or 5 volts, and whether this power is switched/generated by the p&e interface or if it is separately supplied to the target and under user control. if it is under user control, the software will use dialog boxes to ask the user to power the target up and down when necessary (similar to class ii-iv). device clock figure 6-22: device clock selection box the device clock menu allows three options: 1) p&e provides clock to target 2) the target has its own clock (1-32mhz) 3) the target has a slow crystal (30khz-100khz) with pll circuitry. p&e tries to enable the pll to allow programming and debug at higher speeds. baud there is no need to set baud rate for class v, vi, or vii targets, as it is auto- detected from the target.
mon08 cyclone user manual 55 p&e microcomputer systems, inc. mon08 cyclone mon08 cyclone 6.3.1.3 advanced settings dialog the advanced button brings up a dialog which allows the user to set specific protocol settings. the following is an explanation of each part of the advanced settings dialog. figure 6-23: target hardware type: advanced settings dialog tpd and tpu timing these timing parameters are mostly designed for class i boards, although the delays are valid for all classes of boards. many of the ics boards and user target boards need time to power down and power up. whenever power is automatically switched off, or is manually requested to be switched off, the software waits for an amount of time equal to the tpd delay time before proceeding to the connection protocol. this is because a board or power supply may have capacitance which holds the power up for a short time after the supply has been switched off, but the supply voltage must reach less than 0.1v before it is turned back on if a power-on reset is to occur. whenever power is automatically switched on, or is manually requested to be switched on, the software waits for an amount of time equal to the tpu delay time before attempting to contact the 68hc08 processor. this is to allow time not only for power to be fully available, but to wait until any reset driver has finally released the reset line. on many ics08 boards (such as the ics08rk, m68ics08jl3, m68ics08jljk, and ics08gp20) the tpu can be decreased to as little as 250ms with no adverse effects. target has reset button (class iii boards only): the software occasionally needs to get control of the target. on systems which are class iii boards with the monitor mode circuitry built-in (including rs-232 driver), there is no means to reset the target to gain control. if the board has a reset
56 mon08 cyclone user manual p&e microcomputer systems, inc. mon08 cyclone button, the software can use this to gain control of the target system. if this option is checked, the software will prompt the user to push the target reset button when a reset of the target system is desired. if the option is unchecked, the software will ask the user to power cycle the target system to achieve a reset. mon08 cable connection communications type (class ii boards only) this selection box is valid only for class ii hardware configurations using the mon08 cable. it allows the user to specify the sequence that the software uses to power up the ics system. when the software tries to create a power-on reset condition, two events must occur: 1. power of the target mcu must go below 0.1v. this means that the processor can not be receiving power from its power pins, nor can it have a significant voltage being driven on port pins or the irq line, as these will drive the mcu power back through these pins. it is crucial, therefore, to have the ics and the target both powered down at some point in time. 2. the processor mon08 configuration pins, including irq, must be properly driven when the target processor resets to drive it into monitor mode. if these pins are not set up properly before the processor powers up, the processor may start up in user mode. power down ics, ask the user to power down their board, power up ics, ask the user to power up their board this is the default option and should work for most, if not all, ics08/target board solutions. refer to the manual addendum under startup for the settings for a specific ics board. it requires the user go through two dialog stages, and requires more time than simply cycling the power. 1. software automatically powers down the ics. 2. software asks the user to power down the board as follows: figure 6-24: power down dialog 3. software automatically powers up the ics, which configures the processors mon08 configuration pins.
mon08 cyclone user manual 57 p&e microcomputer systems, inc. mon08 cyclone mon08 cyclone 4. software asks the user to power up the board as follows: figure 6-25: power up dialog powerdownics,asktheusertopowercycletheirboard,powerupics this option will work for many ics boards as well, but relies on the fact that while the ics is powered off, it will hold the target in reset until it is powered up itself and has configured the mon08 configuration pins. the sequence of events in this mode is: 1. software automatically powers down the ics. 2. software asks the user to power cycle their board as follows: figure 6-26: power cycle dialog 3. software automatically powers up the ics, which configures the processors mon08 configuration pins. 6.3.2 target mcu security bytes one of the steps that is necessary to properly bypass security is to provide the proper security code for the information that is programmed into the part. this holds true even when the part is blank. the security code consists of the 8 values which are currently stored in flash locations $fff6 - $fffd of the processor. the prog08sz flash programming software continually records any changes to these security bytes and stores them in the file security.ini. the information in this file is shared with p&e's in-circuit debugger and in-circuit simulator software, and will appear in the dialog box. this allows the user to specify which security code to use to pass security.
58 mon08 cyclone user manual p&e microcomputer systems, inc. mon08 cyclone this dialog can also be used by the user to manually enter the proper security bytes via the user setting, or to load the security bytes from the same .s19 file which was programmed. the bytes are loaded from an .s19 file by clicking the load from s19 button. ignore security failure and enter monitor mode this checkbox can be used to cause the software to ignore a failure to properly pass the 68hc08 security check. if the checkbox is set, the software will attempt to establish monitor mode communications regardless of the security status. as long as the baud and port are correct, and the device has been properly powered, this will allow monitor mode entry. note that by ignoring the security check failure, you may use monitor mode, but the rom/flash will not be accessible. the checkbox can be set to be checked on startup via the forcebypass command-line parameter, which will cause the software to ignore security check failure. this checkbox can be overridden to be un checked on startup via the forcepass command-line parameter, which will cause the software to pop-up the connection dialog when the security check has failed. note that if a connection is not established for a reason other than security failure, the connection dialog will always appear. 6.3.3 status the status area consists of one status string following the status: label, and seven items which list the state of the last attempt to connect to a target and pass security. the description for these items is as follows: 0 C ics hardware loopback detected: every ics or board which supports mon08 has a serial loopback in hardware which, by connecting the transmit and receive lines, automatically echoes characters from the pc. a valid character transmitted from the pc should be echoed once by the loopback circuitry on the board and once by the monitor of the target processor itself. this status indicates whether or not the first echoed character from the hardware loopback was received when one of the security bytes was transmitted. if the status is n, which indicates that the character was not received, it is most likely due to one of the following reasons: 1. wrong com port specified. 2. the baud rate specified was incorrect (probably too low). 3. the ics/target is not connected. 4. no power to the ics. if this status bit responded with an n, you must correct this before
mon08 cyclone user manual 59 p&e microcomputer systems, inc. mon08 cyclone mon08 cyclone analyzing the reset of the status bits. 1 C device echoed some security bytes: the monitor resident in a 68hc08 device automatically echoes every incoming character when it is in monitor mode. a valid character transmitted from the pc should be echoed once by the loopback circuitry on the board and once by the monitor of the target processor itself. this status indicates whether or not the second echoed character from the monitor response was received when one of the security bytes was transmitted. if the status is n, which indicates that the character was not received, or not received properly, it is most likely due to one of the following reasons: 1. the baud rate specified was incorrect. 2. the part did not start the monitor mode security check on reset. signals to force monitor mode may be incorrect. 3. no power to the ics. if this status bit responded with an n, you must correct this before analyzing the reset of the status bits. 2 C device echoed all security bytes: in order to pass security, the software must send 8 security bytes to the processor. the processor should echo each of these eight bytes twice. if all 8 bytes did not get the proper two-byte echo, this flag will be n. reasons for this include: 1. the part did not start the monitor mode security check on reset. signals to force monitor mode may be incorrect. 2. the baud rate specified was incorrect. 3. the processor was not reset properly. check the target hardware type and if you are connecting to a class ii board, check the mon08 cable communication connections type in the advanced settings dialog. 3 C device signaled monitor mode with a break: once the processor has properly received the 8 bytes from the pc software to complete its security check, it should transmit a break character to the pc signaling entry into monitor mode. this break should be sent regardless of whether the security check was successfully passed. if a break was not received from the processor, this flag will be n. reasons for this include: 1. the baud rate specified was incorrect. 2. the processor was not reset properly. check the target hardware
60 mon08 cyclone user manual p&e microcomputer systems, inc. mon08 cyclone type. if you are connecting to a class ii board, check the mon08 cable communication connections type in the advanced settings dialog. 4 C device entered monitor mode: once the software has received, or failed to receive, a break from the processor, it attempts to communicate with the monitor running on the 68hc08 processor. it tries to read the monitor version number by issuing a monitor mode read. if the processor fails to respond properly to this command, this flag will be n. 5 C reset was power-on reset: if the device properly entered monitor mode (4), the software will read the reset status register (rsr). this read does not affect the security sequence, and occurs purely for diagnostic reasons. the reset status register indicates the conditions under which the processor underwent the last reset. for the software to pass the security check properly, it must first cause the processor to undergo a power-on reset. the software reads the reset status register to determine if the last reset was indeed caused by power-on. the result of the reset status register is indicated in parentheses after the flag value. if the highest bit is not set then the reset was not a power on reset, and the flag will indicate n. reasons for this include: 1. the processor did not power all the way down because power was being supplied to the processor through either the port pins, irq line, reset line, or power pins. 2. the voltage driven on the power pin of the processor did not go below 0.1 volts. 3. the processor was not reset properly. check the target hardware type. if you are connecting to a class ii board, check the mon08 cable communication connections type in the advanced settings dialog. 6 C rom is accessible (un-secured): if the device properly entered monitor mode (4), the software reads locations $fff6-$ffff to determine if the processor passes the security check. memory locations which are invalid or protected read back from the device as $ad. if all bytes from $fff6-$ffff read a value of $ad, it is assumed the device is secure, and the flag value is an n. if all flags 0-5 register a value of y and flag 6 register a value of n, then the reset process has gone correctly except that the security code used to pass security was incorrect. specify the correct security code and try again, or ignore the security failure and erase the device. once you erase a secured device, you must exit the software and restart it in order to pass
mon08 cyclone user manual 61 p&e microcomputer systems, inc. mon08 cyclone mon08 cyclone security. 6.3.4 additional dialog buttons the following buttons are also available: contact target with these settings C this causes the software to attempt to cause a power on reset of the target, and to attempt to pass security with the settings in this dialog. simulation only C this button is only visible in in-circuit simulation. this causes the in-circuit simulator not to use the target and, instead, to do completely software-based simulation. the /sim08 command-line parameter has the same function. halt C this causes the software to terminate and return to the calling environment. 6.3.5 68hc08 security mode monitor mode is a special mode on the 68hc08 device which allows an external host to control the 68hc08 microcontroller via an asynchronous serial interface. this feature allows a host computer to query and modify the state of the processor including to load, debug, and program code. without any protection mechanism, this same feature could be used to read out the internals of the microcontrollers rom. the m68hc08 microcontrollers have a additional built-in mechanism to protect a programmed device from being read and disassembled. the mechanism allows a user who knows the security unlock code to enter monitor mode and access the internal rom/flash. this is often desirable to allow real- time debugging of a programmed device. the icd08sz allows just such functionality. the security mechanism also allows a user who doesnt know the security code to enter monitor mode, but doesnt give them access to the rom. upon failing the security protocol, the rom/flash is removed from the memory map until the next power-on reset, in which case the host has to bypass security again. the advantage of this is that even though any on-chip flash is not read accessible, it is erasable. forgotten what you programmed into your device? the answer is simple: erase it. a device is automatically protected in this manner. the 8 bytes from address $fff6 to $fffd constitute the security unlock code which can be used to pass the security check and get access to the rom/flash. hence, if a user knows what has been programmed into a device, they implicitly know the security unlock code. in order to facilitate passing the security check on a 68hc08 device, the
62 mon08 cyclone user manual p&e microcomputer systems, inc. mon08 cyclone prog08sz software continually records any changes to these security bytes and stores them in the file security.ini. the information in this file is also shared with p&e's in-circuit debugger and in-circuit simulator software. this allows the user to reset the device and still have access to the monitor mode. sometimes the case comes up where the software cant pass security mode. the target connection and security dialog section has a status section which describes the different failures and what to check in each case. the most common reasons for not passing security are: - you are not choosing the proper security code to pass security. - on a power on reset, the device is not powering down to below 0.1 volts. with a class i board (ics with processor), you may be driving the pins on the emulation header while the device is being powered down. this back-drives current through the ports and doesnt let the device fully power down. on other classes of boards, when prompted to power down the device, the supply voltage might not be dropping lower than 0.1v which it must to have a power-on reset. - make sure the target hardware type is set to the proper class of hardware. there are several ways you can specify the proper security bytes: - if you know the programmed security bytes, i.e. the bytes from $fff6-$fffd, you can enter them in the edit box listed user: and click ok(retry). - you can use the load from s19 to specify the s-record file which contains the object information currently programmed into the mcu. p&es software will automatically extract the security information from this file and use it to pass security. once you have specified the s-record file, click the ok(retry) button. - you can erase the device. run the prog08sz application, and when the above box appears, select the ignore security failure option and click ok. use the choose module command to select the appropriate programming algorithm, and select erase module. this should erase the device. you will have to execute the choose module command again before you can access the blank device. note: on some older revisions of silicon, you cant ignore the security failure, and it will bring this box back up every time you click ok(retry). if this is the case, you should obtain the latest silicon revision from motorola.
