5 chapter 2 connections chapter 2 connections this chapter explains the procedures for connecting the EP-753304du-r, switching on/off its power, and disconnecting the emulation probe from the target system of the EP-753304du-r. 2.1 connection of ie-75001-r and target system the connection procedure is outlined as follows. (1) connecting the ie-75300-r-em and the adapter board (2) connecting the ie-75001-r and the emulation probe (3) connecting the emulation probe and the target system (4) connecting the external sense clips (if external sense clips are used) (5) switching on the power next, the details of each item in the connection procedure are explained.
6 chapter 2 connections (1) connecting ie-75300-r-em and adapter board connect the adapter board to the ie-75300-r-em. <1> while placing a spacer between the ie-75300-r-em and the adapter board, connect the connectors cn1 to cn4 of the ie-75300-r-em and the connectors cn1 to cn4 of the adapter board. <2> fasten the spacer between the ie-75300-r-em and the adapter board using the spacer installation screws. <3> switch off the power of the ie-75001-r. <4> take off the 6 screws on the top of the ie-75001-r unit, then open the units top cover. <5> pull the card pullers on both ends of the board forward and pull out the ie-75000-r-bk note . <6> screw the ie-75300-r-em to the ie-75000-r-bk together. <7> replace the ie-75000-r-bk screwed together with the ie-75300-r-em to the original position of the ie-75001-r. note in the case of the ie-75000-r, the ie-75000-r-em and the ie-75000-r-bk are installed screwed together. therefore, pull out the ie-75000-r-bk from the main unit in the above sequence <3> ?< 4> ?< 5>, remove the screws and pull off the ie-75000-r-em before following steps <1> ?< 2> ?< 6> ?< 7>. figure 2-1. connecting ie-75300-r-em and adapter board cn4 cn1 ie-75300-r-em spacer installation screws adapter board cn5
7 chapter 2 connections (2) connecting ie-75001-r and emulation probe <1> connect the emulation probe to the emulation probe din connector (cn5 of the adapter board) on the top of the ie-75001-r. <2> after connection, be sure to fasten the emulation probe to the ie-75001-r with the installation screws provided. figure 2-2. connecting ie-75001-r and emulation probe ie-75001-r installation screws emulation probe (cn5)
8 chapter 2 connections (3) connecting emulation probe and target system connect the emulation probe to the target system by the following procedure. cautions 1. before connecting the emulation probe to the target system, be sure to connect the ground clip first. otherwise, the ie-75001-r could be damaged by static electricity, etc. 2. when making connections, be careful not to reverse the pins. if connections are incorrect, this could damage the ie-75001-r. <1> switch off the power of the target system. <2> solder the shrink dip socket to the target system. <3> connect the emulation probes ground clip to the ground (gnd) pin of the target system. <4> align the no. 1 pin of the 42-pin shrink dip at the end of the emulation probe with that of the shrink dip socket of <2> soldered into the target system, then insert the emulation probe. figure 2-3. 42-pin shrink dip emulation probe connection in-circuit emulator external sense clips target system shrink dip socket 1 42-pin shrink dip ground clip 42 21 22
9 chapter 2 connections (4) connecting external sense clip the emulation probe is provided with 8 external sense clips which can trace hardware signals on the target system in real time. since the external sense clips are directly connected to the input buffer hct244 inside the in-circuit emulator unit, they have ttl level inputs. the 8 external sense clips are normally input signal lines. however, by setting the out command on the in-circuit emulator, the signal line of external sense clip 1 can be used as an external trigger output signal line in the case of an event (see the in-circuit emulator manual for details). cautions 1. connect the external sense clip to a ttl level signal line only. otherwise, it will not detect the high level and low level accurately. also, depending on the voltage level, the ie-75001-rs sensor could be damaged. 2. before using external sense clip 1 as an external trigger output, ensure that external sense clip 1 is not connected to the signal output line, otherwise a fault may result.
10 chapter 2 connections connect the external sense clip by the following procedure if it is used. <1> switch off the power of the target system first, then that of the ie-75001-r. <2> install the ic clip (commercially available) on the ic which is to be traced in the target system. <3> connect the external sense clip to the ic clip installed. <4> switch on the power to the ie-75001-r first, then that of the target system. figure 2-6. connecting external sense clip remark if an external sense clip is connected, be sure to use an ic clip insofar as possible. this helps prevent faulty contact and improves operability. target system ic external sense clip ic clip
11 chapter 2 connections 2.2 power on and off sequence after the connection of the emulation probe to the target system has been completed, switch on the power. the sequence for switching the power on/off is shown below. caution be sure to follow the correct sequence for switching the power on and off. otherwise, the ie-75001-r could be damaged. (1) if the ie-75001-r is connected to the target system ? power on sequence <1> switch on the power of the ie-75001-r. <2> switch on the power of the target system. ? power off sequence <1> switch off the power of the target system. <2> switch off the power of the ie-75001-r.
12 chapter 2 connections target system shrink dip socket lever extractor 2.3 removing emulation probe from target system remove the emulation probe from the target system by the following procedure. <1> switch off the power of the target system. <2> switch off the power of the ie-75001-r. <3> lift the shrink dip socket lever. <4> pull out vertically the extractor at the end of the emulation probe, and remove the emulation probe from the shrink dip socket. figure 2-7. 42-pin shrink dip emulation probe removal
13 chapter 3 setting mask options chapter 3 setting port 3 the dp1 switch on the adapter board is for the port 3 setting. when these switches are on, pull-up resistors note 1 (47 k w ) or pull-down resistors note 2 (47 k w ) are connected. at shipping, the dp1 switches are set in the off position. notes 1. p33 2. p30 to p32 caution regarding port 3, the setting method for the adapter board and devices differs. the pull-up resistor and the pull-down resistor are set by the dp1 switch. figure 3-1. dp1 switch arrangement diagram 1 off 2 3 4 off p3 14 sw ?bit signal name m pd759000 pin processing 100 w 47 k w usrvdd note 100 w emulation probe p30 to p32 p33 dp1 p30 to p32 p33 dp1? ? p30 ? ? p31 ? ? p32 ? ? p33 47 k w note the same potential voltage of user v dd generated in ie.
