This LSI has a clock pulse generator (CPG) that generates an internal clock (I ), a peripheral clock
(P ), and a bus clock (B ). The CPG consists of oscillators, PLL circuits, and divider circuits.
9.1
A block diagram of the CPG is shown in figure 9.1.
CPGS312B_000020020100
Seven clock modes
Selection of seven clock modes depending on the frequency ranges and crystal oscillation or
external clock input.
Three clocks generated independently
An internal clock for the CPU and cache (I ); a peripheral clock (P ) for the peripheral
modules; a bus clock (B = CKIO) for the external bus interface.
Frequency change function
Internal and peripheral clock frequencies can be changed independently using the phase-locked
loop (PLL) circuit and divider circuit within the CPG. Frequencies are changed by software
using the 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.
