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 3-state output - normal operation
1: Binary output
Limiter select
Limiter selection can be made on a per-channel basis according to the channel limiter select
bits.
Table 59.
Output mapping
Output mapping can be performed on a per channel basis according to the CxOM channel
output mapping bits. Each input into the output configuration engine can receive data from
any of the three processing channel outputs.
