Setting CMC = 1001, initializes the corresponding CFI time slot to be
accessed by the P. Concurrently, the datum in MADR is written (as 8-bit
CFI-idle code) to the CM data field. The content of the CM data field is directly
exchanged with the corresponding time slot.
Note that once the CM code field has been initialized, the CM data field can
be written and read as described in subsection 3.
The CM code can then be read out of the 4 LSBs of the MADR register.
