Bit 3~0: VOL0[3~0] : PSG channel 0 volume control bit

0000 = No sound output

0001 = 1/16 volume

(PSGCK must >= 320K Hz)

0100 = 4/16 volume

1000 = 8/16 volume

1111 = Maximum volume

(PSGCK must >= 20K Hz)

Bit 7~4: VOL1[3~0] : PSG channel 1 volume control bit

0000 = No sound output

0001 = 1/16 volume

(PSGCK must >= 320K Hz)

0100 = 4/16 volume

1000 = 8/16 volume

1111 = Maximum volume

(PSGCK must >= 20K Hz)

Note: If single channel is enable, then PSG volume control can be double. (16

+ 16 = 32 level volume control)
