(1) signals input to or output from the emulation cpu (2) signals input from the target system via a gate (3) lcd-related signals (4) other signals the IE-789831-NS-EM1?s circuit is used as follows for signals listed in (1) to (4) above. (1) signals input to or output from the emulation cpu the following signals perform the same operations as in the pd789830 and the pd78f9831. however, a 1 ? pull-down resistor and 100 ? 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 (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 the pd789830 and the pd78f9831. their ac characteristics and dc characteristics are therefore different from the pd789830 and the pd78f9831 making it necessary to observe a stricter timing design than in the pd789830 and the pd78f9831. ? reset signal ? signals related to clock input in all the signals input from the target system, the reset signal and signals related to clock input are input to the emulation cpu via a logic ic. the dc characteristics are therefore different from the pd789830 and the pd78f9831. chapter 4 differences between target device and target interface circuit user?s manual u14202ej2v0um 34 (3) lcd-related signals because the following signals input/output lcd-related signals, special processing is not performed in the ie- 789831-ns-em1. ?
