1. Writing data to the upstream DM data field (e.g. PCM idle code).
MACR:
MOC3..0 defines the bandwidth and the position of the subchannel as shown below:
Note: When reading a DM data field location, all 8 bits are read regardless of the
2. Writing to the upstream DM code (tristate) field.
MACR:
Note: The tristate field is exchanged with the 4 least significant bits (LSBs) of the MADR.
3. Writing data to the upstream or downstream CM data field (e.g. signaling code).
