General Description
The HT36A3 is an 8-bit high performance RISC-like microcontroller specifically designed for music applications. It provides an 8-bit MCU and a 8 channel wavetable synthesizer. The program ROM is posed of both program control codes and wavetable voice codes, and can be easily programmed. The HT36A3 has a built-in 8-bit microprocessor which programs the synthesizer to generate the melody by setting the special register from 20H~2AH. A HALT feature is provided to reduce power consumption.
