14.1 Function description
The built-in dual channel Programmable Sound Generator
(PSG) is controlled by register file directly. Its flexibility makes it
useful in applications such as music synthesis, sound effects
generation, audible alarms and tone signaling. In order to
generate sound effects while allowing the processor to perform
other tasks, the PSG can continue to produce sound after the
initial commands have been given by the CPU. The structure of
PSG was shown in FIGURE 14-2 and the PSG clock source is
shown in FIGURE 14-1. The ST2202 has three PSG playing
type. One for channel0(C0) & channel1(C1) square type tone
sound playing. Second for ch0 square tone sound and ch1
noise sound. The third sound playing type is DAC PCM playing.
