(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 system?s 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 pd784938a subseries. for the signals related to ports excluding port 7 (having alternate function as a pin for a/d converter), however, a 1 m ? pull-down resistor and 22 ? 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 7 (a/d converter input) ? signals related to port 9 ? signals related to port 10 ? signals related to pwm ? signals for astb/clkout ? signals related to iebus controller ? signals related to a/d converter ? av ref1 ? av ss ? av dd note note 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 between target devices and target interface circuits user?s manual u16556ej1v0um 33 figure 4-1. equivalent circuit 1 of emulation circuit prove side p30 to p37 1 m ? 1 m ? 22 ? p00 to p07 22 ? 1 m ? p10 to p17 22 ? p20 22 ? p21 to p27 22 ? p40 to p47 1 m ? 1 m ? 22 ? p50 to p57 22 ? p66 1 m ? 22 ? p70 to p77 p60 to p65, p67 av ref1 av ss pwm0, pwm1 astb/clkout p100 to p107 1 m ? 22 ? p90 to p97 1 m ? 22 ? sw1 altera epm7064-10 lv cc 4.7 k ? sw1 av dd open lv cc tx, rx ie system side 22 ? chapter 4 differences between target devices and target interface circuits user?s manual u16556ej1v0um 34 (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 pd784938a subseries. their ac characteristics and dc characteristics are therefore different from pd784938a subseries, making it necessary to observe a stricter timing design than in the case of pd784938a subseries. ? reset signal ? signals related to clock input figure 4-2. equivalent circuit 2 of emulation circuit lv cc 4.7 k ? v cc 4.7 k ? 24 ? altera epm7128-15 vhc244 reset reset vhc244 clk in x1 x2 input output open IE-784937-NS-EM1 umclk mounted clock act86 rzt025p input output act86 rzt025p multiplier multiplier 1 2 3 jp3 als157 als157 remark when using the IE-784937-NS-EM1 with the ie-78k4-ns, set jp3 with 1 and 2 shorted. chapter 4 differences between target devices and target interface circuits user ? s manual u16556ej1v0um 35 figure 4-3. equivalent circuit 3 of emulation circuit 10 m ? 470 k ? vhc244 xt1, xt2, ic/v pp open v cc 4.7 k ? ic socket usclk hcu04 hcu04 68 22 pf 22 pf 32.768 khz ie system side probe side (3) other signals ? v dd pin when the emulation cpu is operating at 5 v, its power is supplied from the internal ie system, but when operating at low voltage, its power is supplied from the low-voltage pin (tp1). the v dd pin of the target system is only used to control the led (userv dd ) in the ie system that monitors the input of the target system ? s power supply. ? v ss pin the v ss pin is connected to gnd inside the ie system. user?s manual u16556ej1v0um 36 chapter 5 restrictions the IE-784937-NS-EM1 has the following restrictions. ? the specification of the stop mode of the watch timer function is different from that of the target device. when the count clock is selected as the main clock, the timer stops in the target device in stop mode, however, the timer does not stop in the IE-784937-NS-EM1. user?s manual u16556ej1v0um 37 chapter 6 cautions when using the IE-784937-NS-EM1, observe the cautions below. ? set the IE-784937-NS-EM1 as follows when using it in combination with the ie-78k4-r-ex3 in the ie-784000-r. note that the setting described in 3.1 installation procedure (2) of the ie-78k4-r-ex3 user?s manual (u16346e) is not required.
