(1) signals input to or output from the eva chip and the peripheral eva chip (2) signals input from the target system via a gate (3) other signals the ie-789801-ns- em1?s circuit is used as follows for signals listed in (1) to (3) above. chapter 4 differences between target devices and target interface circuits user?s manual u13390ej2v0um 33 (1) signals input to or output from the eva chip and the peripheral eva chip the following signals perform the same operations as in the pd789800 subseries. ?
