MCC Configuration Registers (MCCF

x)

The MCC configuration register (MCCF), shown in

Figure 28-17

, 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).

Table 28-15

describes MCCF fields.
