28.6 MCC Configuration Registers (MCCF
x
)

The MCC configuration register (MCCF), shown in Figure28-17, defines the mapping of the MCC

channels to the TDM channels. MCC1 can be connected to SI1 and MCC2 can be connected to SI2. For

each MCCx-SIx pair, each of the four 32 channels subgroups can be connected to one of the four TDM

highways (TDMA, TDMB, TDMC, and TDMD).

Table28-15 describes M CCF fields.
