Channel configuration registers ( 0x0E to 0x10)
Tone control bypass
Tone control (bass/treble) can be bypassed on a per channel basis for channels 1 and 2.
CxTCB:
0: perform tone control on channel X, normal operation
1: bypass tone control on channel X
EQ bypass
EQ control can be bypassed on a per channel basis for channels 1 and 2. If EQ control is
bypassed on a given channel the prescale and all filters (high-pass, biquads, de-emphasis,
bass, treble in any combination) are bypassed for that channel.
CxEQBP:
0: perform EQ on channel X, normal operation
1: bypass EQ on channel X
Volume bypass
Each channel contains an individual channel volume bypass. If a particular channel has
volume bypassed via the CxVBP = 1 register then only the channel volume setting for that
particular channel affects the volume setting, the master volume setting will not affect that
channel.
Binary output enable registers
Each individual channel output can be set to output a binary PWM stream. In this mode
output A of a channel is considered the positive output and output B is negative inverse.
CxBO:
0: DDX tri-state output, normal operation
1: binary output
