Along with SYNTH_DENOM, this sets the clock divider that generates the Port 1 or Port 2 clock in
master mode.
Along with SYNTH_NUM, this sets the clock divider that generates the Port 1 or Port 2 clock in master
mode.
This sets the number of clock cycles before the sync pattern repeats. This depends if the audio port
data is mono or stereo.
In MONO mode:
