It provides an 8-bit MCU and a 8 channel wavetable synthesizer. The program ROM is composed of both program control codes and wavetable voice codes, and can be easily programmed. The HT36A1 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 P A 0 ~ P A 7 P B 0 ~ P B 7 P C 0 ~ P C 7 O S C 1 O S C 2 R E S 6 4 K ´ 1 6 - b it R O M 8 -...
