IDLE_PATTERN
When this programmed pattern matches the received byte for the associated
channel, the channel is considered to be idle. The conditions which qualify a
match are controlled by the PAT_MTCH_CFG register.
PAT_MASK
When a bit is set in this mask field the bit will not be factored into the pattern
matching function and therefore will be considered a “don’t care” bit.

TX_MASK
These bits are used as a mask on the TX_CAS field. Only changes in
unmasked CAS bits will cause an interrupt to the processor.
RX_MASK
These bits are used as a mask on the RX_CAS field. Only changes in
unmasked CAS bits will cause an interrupt to the processor.
