　　1. general deion

　　this flash rom-based 8-bit micro-controller uses a fully

　　static cmos technology process to achieve higher speed

　　and smaller size with the low power consumption and

　　high noise immunity. on chip memory includes 4k words

　　of rom, 256 bytes of eeprom and 192 bytes of static

　　ram.
