Note that after a clock source is selected, the clock is given an internal name. For the FCCs
and SCCs, the names are RCLKx and TCLKx; for SMCs, the name is simply SMCLKx.
These internal names are used only in NMSI mode to specify the clocks sent to the FCCs,
SCCs or SMCs. These names do not correspond to any MPC8260 pins.
15.4 CMX Registers
The following sections describe the CMX registers.
