The 4-bit code field of the control memory (CM) defines the functionality of a
CFI time slot and thus the meaning of the corresponding data field. This 4-bit
code, written to the MACR:CMC3..0 bit positions, will be transferred to the
CM-code field. The 8-bit MADR value is at the same time transferred to the
CM-data field. There are codes for switching applications, pre-processed
applications and for direct P-access applications, as shown below:
