10.1
The on-chip oscillation circuits consist of the clock pulse generator (CPG) and watchdog timer
(WDT).
The clock pulse generator (CPG) supplies all clocks to the processor and controls the power-down
modes.
The watchdog timer (WDT) is a single-channel timer that counts the clock settling time and is
used when clearing standby mode and temporary standby, such as frequency changes. It can also
be used as an ordinary watchdog timer or interval timer.
10.1.1
The CPG has the following features:
• Four clock modes: Selection of four clock modes for different frequency ranges, power
• Three clocks generated independently: An internal clock for the CPU, cache, and TLB (Iφ); a
• Frequency change function: Internal and peripheral clock frequencies can be changed
• Power-down mode control: The clock can be stopped for sleep mode and standby mode and
consumption, direct crystal input, and external clock input.
peripheral clock (Pφ) for the on-chip supporting modules; and a bus clock (CKIO) for the
external bus interface.
independently using the PLL circuit and divider circuit within the CPG. Frequencies are
changed by software using frequency control register (FRQCR) settings.
specific modules can be stopped using the module standby function.
