General Description
The
APU429
is an embedded high performance
4-bit micro-computer with an on-chip LCD driver. It
contains all the necessary functions in a single chip:
4-bit parallel processing ALU, ROM, RAM, I/O ports,
timer, clock generator, dual clock, RFC, EL-light,
LCD driver, look-up table, watchdog timer and
keyboard scanning. The instruction set includes not
only 4-bit operation and manipulation instructions
but also various conditional branch instructions and
LCD driver data transfer instructions which are
powerful and easy to use.
The HALT function stops any internal operations
other than the oscillator, divider and LCD driver in
order to minimize the power dissipation.
The STOP function stops all the clocks in the chip.
