belong to the 78k/0 series of 8-bit single-chip microcontrollers. ? pd780958 subseries: pd780957(a), 780958(a) target readers this manual is intended for engineers who will use the IE-780958-NS-EM4 with the ie- 78k0-ns or ie-78k0-ns-a and ie-78k0-ns-p02 to perform system debugging. engineers who use this manual are expected to be thoroughly familiar with the target device?s functions and use methods and to be knowledgeable about debugging. organization when using the IE-780958-NS-EM4, refer to not only this manual (supplied with the ie- 780958-ns-em4) but also the manuals that are supplied with the ie-78k0-ns-p02 and the ie-78k0-ns or ie-78k0-ns-a. the ie-78k0-ns used in combination with the ie-78k0-ns-pa is functionally equivalent to the ie-78k0-ns-a. therefore, as necessary, read ie-78k0-ns + ie-78k0-ns-pa for ie-78k0-ns-a in this document. ie-78k0-ns or ie-78k0-ns-a IE-780958-NS-EM4 user?s manual user?s manual ? basic specifications ? general ? system configuration ?
