The usual Holtek microcontroller features of low power consumption, I/O flexibility, timer functions, oscillator options, power down and wake-up functions, watchdog timer and low voltage reset, bine to provide devices with a huge range of functional options while still main- taining a high level of cost effectiveness. The fully integrated system oscillator HIRC, which requires no external ponents and which has three frequency selections, opens up a huge range of new application possibilities for these devices, some of which may include industrial control, consumer products, household appliances subsystem controllers, etc. Rev....
