■ DESCRIPTION
The MB89120 series is a line of single-chip microcontrollers
containing a compact instruction set and a great variety of
peripheral functions such as a timer, serial interface, and
external interrupt. The MB89120A series is an extended variant of
the MB89120, with a remote control transmission function and
wake-up interrupt function.
