6.9.3

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.

6.9.4

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

6.9.5

Limiter select

Limiter selection can be made on a per-channel basis according to the channel limiter select

bits.

6.9.6

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.
