Register description
46/67
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.
Table 61.
Limiter select
Limiter selection can be made on a per-channel basis according to the channel limiter select
bits.
Table 62.
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.
