RESET CIRCUIT
When batteries are set or an AC adapter is connected, the reset IC provides a low pulse to the CPU. The CPU
then initializes its internal circuit.
When the power switch is pressed, the CPU receives a low pulse of POWER signal.The CPU raises APO signal
to +5 V to turn power on.

CPU (LSI101: UPD912GF-3BA)
The 16-bit CPU contains a 1k-byte RAM, three 8-bit I/O ports, two timers, a keycontroller and serial interfaces.
The CPU detects key velocity by counting the time between first-key input signal FI and second-key SI from
the keyboard. The CPU reads sound data and velocity data from the sound source ROM in accordance with
the selected tone; the CPU can read rhythm data simultaneously when a rhythm pattern is selected. Then the
CPU provides 16-bit serial sound data to the DAC.The CPU also controls MIDI input/output and LED driving.

DAC (IC103: UPD6379GR)
The DAC receives 16-bit serial data output from the CPU. The data contains digital sound data of the melody,
chord, bass, and percussion for the right and left channels. The DAC converts the data into analog waveforms
and output them to each channel separately.
