DESCRIPTION
a fluorescent display tube controller/driver, a watch timer, a timer/pulse generator capable of outputting 14-bit PWM,
a serial interface and a vectored interrupt function integrated on a single-chip.
applications requiring the timer/watch function and high-speed interrupt servicing. It can help to provide the unit
with many functions and to decrease performance costs.
