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 HT36A0 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. Block Diagram V D V S V D V S S 1 6 - B it D A C 1 6 - B it D A C D D A S A ...
