GENERAL DESCRIPTION
The MTU419B is an embedded high-performance 4-bit microcomputer with 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, alarm, EL-light, LCD driver, look-up table and watchdog timer. The instruction set consists of 135 instructions which include nibble operation, manipulation various conditional branch instructions and LCD data transfer instructions which are powerful and easy to follow.
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.
