General Description
The HT36B0 is an 8-bit high performance RISC-like
microcontroller specifically designed for music applica-
tions. It provides an 8-bit MCU and a 16 channel
wavetable synthesizer. The program ROM is composed
of both program control codes and wavetable voice
codes, and can be easily programmed.
The HT36B0 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 fea-
ture is provided to reduce power consumption.
