family, with additional instruc-
tions for use with high-level languages, expanded addressing mode, enhanced multiply and divide instructions,
and full bit processing. Also included is a built-in 32-bit accumulator for long-word processing.
Peripheral resources built into the MB90470 series include 8/16-bit PPG, expanded I/O serial interface, UART,
10-bit A/D converter, 16-bit input-output timer, 8/16-bit up-counter, PWC timer, I
