GENERAL DESCRIPTION
The MSM66573 family of highly functional CMOS 16-bit single chip microcontrollers utilize the nX-8/500S, Oki's proprietary CPU core.
A wide variety of internal multi-functioned timers provide timer functions such as compare out, capture, event counter, auto reload, and PWM, and can be used for periodic and timed measurements. In addition to the main clock and clock gear functions, there is a sub clock (32.768 kHz) that is suitable for low power applications. A three channel serial interface and a high-speed bus interface that has separate address and data buses and does not require external address latches are provided as interfaces to external devices.
