General Description
The device is an 8-bit high performance RISC-like
microcontroller designed for multiple I/O product appli-
cations. It is particularly suitable for use in products
such as washing machine controllers, camera control-
lers and home appliances with LCD display. A HALT
feature is included to reduce power consumption.
