(1) signals input to or output from the evaluation chip and peripheral evaluation chip (2) signals input from the target system via a gate (3) other signals the IE-789026-NS-EM1?s circuit is used as follows for signals listed in (1) to (3) above. (1) signals input to or output from the evaluation chip and peripheral evaluation chip the following signals perform the same operations as in the pd789026 subseries. however, a 1 m ? pull-down resistor and 100 ?
