The value in these down counters are reloaded after the 160 counts from the binary/decade counter combination. When these down counters are loaded, the TC signal is clear, which mutes the voice. When the down counters cross through 0, the TC signal goes high and the 4016 multiplexers allow the AY-8910 voice to go through. Thus, writing a 0 to the counters will enable the voice for the longest period of time, while writing a 15 enables it for the shortest period of time. This creates an effective duty cycle for the voice. Given that the down counters are reset 50000 times per second (SSIO_CLOCK/2/160), which is above the typical frequency of sound output. So we simply apply a volume adjustment to each voice according to the duty cycle. */

The value in these down counters are reloaded after the 160 counts from the binary/decade counter combination. When these down counters are loaded, the TC signal is clear, which mutes the voice. When the down counters cross through 0, the TC signal goes high and the 4016 multiplexers allow the AY-8910 voice to go through. Thus, writing a 0 to the counters will enable the voice for the longest period of time, while writing a 15 enables it for the shortest period of time. This creates an effective duty cycle for the voice. Given that the down counters are reset 50000 times per second (SSIO_CLOCK/2/160), which is above the typical frequency of sound output. So we simply apply a volume adjustment to each voice according to the duty cycle.
