users manual u13743ej1v0um00 37 chapter 4 differences between target devices and target interface circuits this chapter describes differences between the target devices signal lines and the signal lines of the ie-784908- ns-em1s target interface circuit. although the target device is a cmos circuit, the IE-784908-NS-EM1s target interface circuit consists of an emulation cpu, ttl, cmos-ic, and other emulation circuits. when the ie system is connected with the target system for debugging, the ie system performs emulation so as to operate as the actual target device would operate in the target system. however, some minor differences exist since the operations are performed via the ie systems emulation. (1) signals directly input/output to/from the emulation cpu (2) signals input from the target system via a gate (3) other signals the ie systems circuit is used as follows for signals listed in (1) to (3) above. (1) signals directly input/output to/from the emulation cpu the following signals perform the same operations as in the m pd784908 subseries. for the signals related to ports excluding port 7 (having alternate functions as pins for a/d converter), however, a 1-m w pull-down resistor and 22- w resistor are inserted in series. signals related to port 0 signals related to port 1 signals related to port 2 signals related to port 3 signals related to port 4 signals related to port 5 signals related to port 6 signals related to port 7 (a/d converter input) signals related to port 9 signals related to port 10 signals related to a/d converter av ref av ss signals related to pwm astb/clkout iebus tm interface signal tx, rx remark the av dd pin on the target system is not connected to the ie system. either the power supply of the ie system or the power supply supplied to tp1 is supplied to the av dd pin of the emulation cpu.

chapter 4 differences among target devices and target interface circuits users manual u13743ej1v0um00 39 (2) signals input from the target system via a gate since the following signals are input via a gate, their timing shows a delay compared to that of the m pd784908 subseries. their ac characteristics and dc characteristics are therefore different from m pd784908 subseries, making it necessary to observe a stricter timing design than in the case of m pd784908 subseries. reset signal signals related to clock input figure 4-2. equivalent circuit 2 of emulation circuit lv cc 4.7 k w 27 w ie system side probe side altera epm7128-15 vhc244 vhc244 reset reset x1 x2 xt1 xt2 clk in tck in 1 2 3 x1 mounted clock multiplier multiplier als157 jp1 als157 leave open x2 mounted clock leave open leave open caution set jp1 to 1 and 2 shorted.
