Receive channel on DD, transmit channel on DU.
Receive channel on DU, transmit channel on DD.
Receive monitor channnel inactive
Receive monitor channel active
No acknowledgement is sent in response to a received byte.
When MRE = 1 and MRC = 0, only the first byte of a packet can
received, further bytes (in the case that the first byte is
acknowledged by another IC) are not loaded into MONR.
Acknowledgement via MR bit is enabled, acknowledgement
takes place after MONR is read.
Transmit monitor channel inactive (high impedance)
Monitor channel transmission enabled
