bus
interface that allows inter-equipment communication to be implemented readily. This product is well adapted to
car audio equipment, VTR systems, and other equipment and systems.
The instruction set of F

family with additional instruction
sets for high-level languages, extended addressing mode, enhanced multiplication/division instructions, and en-
hanced bit manipulation instructions. The microcontroller has a 32-bit accumulator for processing long word data.
The MB90570 series has peripheral resources of an 8/10-bit A/D converter, an 8-bit D/A converter, UART (SCI),
an extended I/O serial interface, an 8/16-bit up/down counter/timer, an 8/16-bit PPG timer, I/O timer (a 16-bit free
run timer, an input capture (ICU), an output compare (OCU)).
