17、e 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 C

18、PU 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 accord
