* Preventing Latchup
When CMOS integrated circuit devices are subjected to applied voltages higher than Vcc at input and output pins (other than medium- and high-withstand voltage pins), or to voltages lower than Vss, as well as when voltages in excess of rated levels are applied between Vcc and Vss, a phenomenon known as latchup can occur. When a latchup condition occurs, supply current can increase dramatically and may destroy semiconductor elements. In using semiconductor devices, always take sufficient care to avoid exceeding maximum ratings.
* Treatment of unused input pins
If unused input pins are left open, abnormal operation may result. Any unused input pins should be connected to pull-up or pull-down resistance.
* Power supply pins
Devices are designed to prevent problems such as latchup when multiple Vcc and Vss supply pins are used, by providing internal connections between pins having the same potential. However, in order to reduce unwanted radiation, prevent abnormal operation of strobe signals due to rise in ground level, and to maintain total output current ratings, all such pins should always be connected externally to power supplies and ground. Also, care must be given to connecting the Vcc and Vss pins of this device to a current source with as little impedance as possible. In addition, it is recommended that a bypass capacitor of 1.0 F be connected between Vcc and Vss as close to the pins as possible.
* Crystal oscillators
Noise in proximity to the X0 and X1 pins can cause abnormal operation in this device. Printed circuit boards should be designed so that the X0 and X1 pins, and oscillators (or crystal oscillators), as well as bypass capacitors connected to ground, are placed as close together as possible. The use of printed circuit board architecture in which the X0 and X1 pins are surrounded by ground contributes to stable operation and is strongly recommended.
* Treatment of NC pins
Any pins marked "NC" (not connected) must be left open.
* Mode pins (MD0-MD2)
These pins should be used in direct connection to Vcc or Vss. To prevent noise from causing the device to erroneously switch into test mode, the printed circuit board design should allow the shortest possible pattern length between mode pins and Vcc or Vss, and the connection should have as little impedance as possible.
* Operation at startup
Immediately after a power-on startup, always apply a reset initialization (INIT) at the INIT pin. Also, in order to assure a wait period for the oscillator circuits to stabilize immediately after startup, be sure that the "L" level input to the INIT pin continues for the required stabilization wait interval. (The INIT cycle for the INIT pin includes only the minimum setting for the stabilization wait period.)
* Base oscillator input at startup
At power-on startup, always input a clock signal until the oscillator stabilization wait period is ended. 14
MB91307B
* Hardware standby at power-on startup
If a power-on startup is followed immediately by a hardware standby request, the reset initialization of settings (INIT) from the INIT pin has priority. However in case of transition from the reset initialization (INIT) to hardware standby, the oscillator stabilization wait period is initialized to maximum duration, and after release of the hardware standby request the maximum setting is applied to the oscillator stabilization wait period.
* Caution on Operations during PLL Clock Mode
If the PLL clock mode is selected, the microcontroller attempt to be working with the self-oscillating circuit even when there is no external oscillator or external clock input is stopped. Performance of this operation, however, cannot be guaranteed.
* Remarks for the external clock operation
When selecting the external clock, active X0 pin generally. Also simultaneously the opposite phase clock to X0 must be supplied to X1 pin. When using the clock along with STOP (oscillation stopped) mode, the X1 pin stops when "H" is input in STOP mode. To prevent one output from competing against another, in this case, the stop mode must not be used.

Using external clock (normal) Note : Stop mode (oscillation stop mode) cannot be used. Refer to the Data Sheet for maximum input frequency.
* Built-in DC-DC regulator
This device has a built-in regulator, requiring 3.3 V input to the Vcc pin and a bypass capacitor of approximately 0.1 F connected to the C pin for the regulator. Note that the A/D converter requires a separate 3.3 V power supply.

* Precautions for use of stop mode
The built-in regulator in this device stops operating when the device is in stop mode. In such cases as when increased leak current (ICCH) in stop mode, or abnormal operation or power fluctuation due to noise while in operating mode cause the regulator to stop, the internal 2.5 V power supply can ball below the voltage at which operation is assured. Therefore it is necessary when using the internal regulator and stop mode to assure that the external power supply does not fall below 3.3 V. And even if this should occur, the internal regulator can be set to restart when a reset is applied. (In this case the oscillator stabilization wait period should also be set to L level.)

* To enter the standby mode, use the synchronous standby mode (set with the SYNCS bit as bit 8 in the TBCR, or time-base counter control register) and be sure to use the following sequence: (LDI #value_of_standby, R0) (LDI #_STCR, R12) STB R0, @R12 ; Write to standby control register (STCR) LDUB @R12, R0 ; Read STCR for synchronous standby LDUB @R12, R0 ; Read STCR again for dummy read NOP ; NOP x 5 for timing adjustment NOP NOP NOP NOP Set the I-flag and the ILM and ICR registers to branch to an interrupt handler when the interrupt handler triggers the microcontroller to return from the standby mode. * If you use the monitor debugger, follow the precautions below: Do not set a breakpoint within the above array of instructions. Do not single-step the above array of instructions.
* Executing instructions on RAM
If instruction codes are placed in RAM, they should not be placed in the last 8 address bytes 0005_FFFF8H to 0005_FFFFH. (Instruction code prohibited area)

* Notes on the PS register
Since some instructions manipulate the PS register earlier, the following exceptions may cause the interrupt handler to break or the PS flag to update its display setting when the debugger is being used. As the microcontroller is designed to carry out reprocessing correctly upon returning from such an EIT event, it performs operations before and after the EIT as specified in either case. * The following operations may be performed when the instruction immediately followed by a DIVOU/DIVOS instruction is (a) halted by a user interrupt or NMI, (b) single-stepped, or (c) breaks in response to a data event or emulator menu: (1) D0 and D1 flags are updated earlier. (2) The EIT handler (user interrupt/NMI or emulator) is executed. (3) Upon returning from the EIT, the DIVOU/DIVOS instruction is executed and the D0 and D1 flags are updated to the same values as those in (1) above. * The following operations are performed when the ORCCR/STILM/MOV Ri and PS instructions are executed to enable interruptions when a user interrupt or NMI trigger event has occurred. (1) The PS register is updated earlier. (2) The EIT handler (user interrupt/NMI or emulator) is executed. (3) Upon returning from the EIT, the above instructions are executed and the PS register is updated to the same value as that in (1) above.
* Notes on I-BUS Memory
Do not access data in the instruction cache control register or the instruction cache RAM immediately before the RETI instruction.
rUnique to the evaluation chip MB91V307R
* Simultaneous occurrences of a software break and a user interrupt/NMI
When a software break and a user interrupt /NMI take place at the same time, the emulator debugger can cause the following phenomena: * The debugger stops pointing to a location other than the programmed breakpoints. * The halted program is not re-executed correctly. If these phenomena occur, use a hardware break instead of the software break. If the monitor debugger has been used, avoid setting any break at the relevant location.
* Single-stepping the RETI instruction
If an interrupt occurs frequently during single stepping, execute only the relevant processing routine repeatedly after single-stepping RETI. This will prevent the main routine and low-interrupt-level programs from being executed. Do not single-step the RETI instruction for avoidance purposes. When the debugging of the relevant interrupt routine becomes unnecessary, perform debugging with that interrupt disabled.
* A stack pointer placed in an area set for a DSU operand break can cause a malfunction. Do not apply a data event break to access to the area containing the address of a system stack pointer.

s SETTING MODE
In the FR family, the mode pins (MD2, MD1, MD0) and the mode register (MODR) are used to set the operating mode.
1. Mode Pins
The three pins MD2, MD1, MD0 are used in mode vector fetch instructions, and also to make settings in test mode. Mode pin Reset vector access Mode name Remarks area MD2 MD1 MD0 0 0 1 External ROM mode vector Outside Bus width is set by mode register.
2. Mode Register (MODR)
The mode data fetch instruction writes data to the address "0000_07FDH" called the mode data. The area "0000_07FDH" is the mode register (MODR). When a setting is made to this register, the device will operate the mode corresponding to that setting. The mode register can only be set by a reset source at the INIT level. It is not possible to write to this register from a user program.
No data exists at the FR family mode register address (0000_07FFH). < Detailed register description >

s MEMORY SPACE
1. Memory Space
The FR family has 4 GB (232 addresses) of logical address space with linear access from the CPU. *Direct Addressing Areas The following areas of address space are used for I/O operations. These areas are called direct addressing areas, in which the address of an operand can be specified directly during an instruction. The direct areas differ according to the size of the data accessed, as follows. byte data access : 0-0FFH half word data access : 0-1FFH word data access : 0-3FFH

*Use of Built-in RAM The MB91307B provides 128 KB of built-in RAM. To enable use of this RAM, the mode register must be set to internal ROM external bus mode (ROMA=1). Precautions for use of this model * The reset vector is fixed at 000F_FFFCH. * For the MB91307B, the 128Kbyte RAM area is from 0004_0000H to 0005_FFFFH. The area from 0006_0000H to 000F_FFFFH is access prohibited. * In order to use RAM the mode register must be set to internal ROM external bus mode. * In internal ROM external bus mode the built-in RAM area can be used, but the vector area 000F_FFXXH is an internal area and cannot be accessed externally. Please refer to the following explanation. * When placing instruction code in RAM, nothing should be placed in the last 8 bytes of the area 0005_FFFF8h to 0005_FFFFH. (This is an instruction code prohibited area.)

s USER PROGRAM INITIALIZATION
The following sequence describes an example using built-in RAM.
1. Hardware Setting Conditions
MB91307B
CS0
External ROM
Normal setting
A19-1
1) Assume that 1 MB of external ROM is placed beginning at 0010_0000H. Place the program at this location in the linker. (The following description can apply to other addresses than this one as well.) 2) Connect addresses A19 to A1 (1 MB) to ROM, other addresses will use CS0. 3) Set the mode pins (MD2, MD1, MD0) to external vectors. 4) Write the reset vector to 001F_FFFCH. Likewise write the mode vector to 001F_FFF8H.
2. Immediately After Reset Release
0000_0000H
MB91307B
CS0
External ROM
0004_0000H External ROM
FFFF_FFFFH
1 MB of ROM can be viewed again on the address map.
1)
After reset release, the CPU will attempt to load a mode vector from 000F_FFF8H , a reset vector from 000F_FFFCH, however because this will be an external vector, the CPU will have to go externally. However the CS0 default value causes 1 MB of external ROM to be repeated in external space, so that the mode vector and the reset vector itself will load the contents written at 001F_FFF8H and 001F_FFFCH in external ROM. 2) The branch destination is set in the linker to an address in the area 001X_XXXXH, so that subsequent program execution will be in this area.
28
MB91307B
3. User Program Initialization Steps
0000_0000H
MB91307B
CS0
External ROM
0004_0000H
0010_0000H External ROM 001F_FFFFH FFFF_FFFFH
1 MB of ROM space matches 1 MB of the address map.
1) Set the TBR register so that the interrupt table is 001F_FFXXH, then perform initialization. This process also includes a chip select setting, and at the same time the CS0 address is set to be valid at 001X_XXXXH. The CS0 decoding result is the same before and after the setting, so that the CPU can continue to run programs on external ROM. 2) If necessary, initialize the contents of RAM. 3) Now initialization is complete, and the application program can be executed.

4. 16-bit Reload Timer
(1) Overview The 16-bit timer is configured from a 16-bit down-counter, 16-bit reload register, prescaler for internal count clock generation, and a control register. For the input clock signal, a selection of three internal clock signals (machine clock multiplied by 2, 8, or 32) or external clock is provided. The output pin (TOUT) produces a toggle output waveform at every underflow in reload mode, and a square wave indicating counting in progress in one-shot mode. The input pin (TIN) can be used for event input in external event count mode, and trigger input or gate input in internal clock mode. The external event count function can be used in reload mode or as a frequency multiplier in external clock mode. There are three built-in 16-bit reload timer channels on this device. Channels 0 1and 1 can be used to start DMA transfer from an interrupt signal. (2) Register List

5. U-TIMER (16 bit timer for UART baud rate generation)
(1) Overview The U-TIMER is a 16-bit timer used to generate the baud rate for the UART. Any desired baud rate can be set using the combination of chip operating frequency and U-TIMER reload value. The U-TIMER can also be used as an interval timer by generating an interrupt from a count underflow event. This device features a 3-channel built-in U-TIMER. By connecting two U-TIMER channels used as interval timers in a cascade connection, it is possible to count intervals up to a maximum of 232 x . The available case connections are channel 0 to channel 1, and channel 1 to channel 2. (2) Register List

Precautions for Use: When the A/D converter is started from an external trigger or internal timer, the ADCS register A/D start source bits STS1, 0 are set, and at this time the input values for the external trigger and internal timer should be set to the inactive side. If these values are set to the active side, abnormal operation may result. When setting the STS 1, 0 bits, set ATG = "1" input, reload timer (channel 2) = "0" output. Caution: If internal impedance is higher than the specified value, it may not be possible to obtain analog input value sampling within the specified sampling time, so that proper results will not be obtained.
