The clock pulse generator (CPG) supplies all clocks to the processor and controls the power-down
modes. A block diagram of the clock pulse generator is shown in figure 10.1.
10.1
The CPG has the following features:
Four clock modes: Selection of 4 clock modes for different frequency ranges, power
consumption, direct crystal input, and external clock input are available.
Three clocks generated independently: An internal clock for the CPU, cache, and TLB (I ); a
peripheral clock (P ) for the on-chip supporting modules; and a bus clock (CKIO) for the
external bus interface.
Frequency change function: CPU and peripheral clock frequencies can be changed
independently using the PLL circuit and divider circuit within the CPG. Frequencies are
changed by software using frequency control register (FRQCR) settings.
Power-down mode control: The clock can be stopped for sleep mode and software standby
mode and specific modules can be stopped using the module standby function.
