Limiter select
Limiter selection can be made on a per-channel basis according to the channel limiter select
bits.
Table 60.
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.
