General Description
The device is an 8-bit high performance RISC architec-
ture microcontroller specifically designed for various
Music and ADPCM applications. It provides an 8-bit
MCU and 4-channel Wavetable synthesizer. It has a in-
tegrated 8-bit micro controller which controls the syn-
thesizer to generate the melody by setting the special
register. A Power-down function is included to reduce
power consumption.
