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 feature is provided to reduce power consumption. Block Diagram 2 * 2 * , 2, , 1 1 1, , * EJ + 7 > EJ 4 4 ) K JEF EA H2 D = I A / A A H= 5 JA HA * EJ, ) + ) ) , + ),, 7 6 Rev June 30, 2003
