Reference Clock Frequency Dividers

There are many clock frequency dividers in the PMC, LPD, FPD, and CPM that provide a reference clock for each block or group of blocks. See the Clock Distribution section for an overview.

The PMC, processing system, and CPM clock dividers all have similar programming models. The clock control registers select the PLL source clock, the 10-bit frequency divider value, and enable the divider clock output. The clock divider register sets include:

• CRP register module for PMC clocks
• CRL register module for LPD clocks
• CRF register module for FPD clocks
• CPM4_CRX register module for CPM4 clocks
