Once an UP, DN or MUTE button has been validly pushed,
the left and right inputs are examined for Zero Amplitude
Crossing. When either audio input exhibits a zero crossing
prior to 32ms, that command is immediately applied to
appropriate wiper. If the zero crossing does not occur before
the end of 32ms, the command is executed at the end of
32ms period. Zero crossing determines for each channel
independently.
There is a 40ms lockout time after any of the UP, DN or
MUTE button has been validly pushed, when any new
command is ignored. If two or more buttons are pressed
simultaneously, all commands are ignored upon release of
ALL buttons.
