CPU (LSI1: GT-913F)

The 16-bit CPU contains a 1k-byte RAM, three 8-bit I/O ports, two timers, a key controller 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 DSP. The CPU also controls MIDI input/output and stores

sequencer data into the working storage RAM.

The following table shows the pin functions of LSI1.
