The control and data memories must be accessed by the P in order to initialize the CFI
and PCM interfaces for the required functionality, to program time slot assignments, to
access the control/signaling channels (IOM/SLD), etc.
This access is performed through indirect addressing using the memory access
registers MADR, MAAR, and MACR.
