This LSI has a clock pulse generator (CPG) that generates an internal clock (Iφ), a bus clock (Bφ),
a peripheral clock (Pφ), and a clock (MPφ) for the MTU2 module. The CPG also controls power-
down modes.
4.1
• Five clocks generated independently
• Frequency change function
• Power-down mode control
• Oscillation stop detection
CPGS301C_000020030900
An internal clock (Iφ) for the CPU; a peripheral clock (Pφ) for the on-chip peripheral modules;
a bus clock (Bφ = CK) for the external bus interface; and a MTU2 clock (MPφ) for the on-chip
MTU2 module.
Frequencies of the internal clock (Iφ), bus clock (Bφ), peripheral clock (Pφ), and MTU2 clock
(MPφ) can be changed independently using the divider circuit within the CPG. Frequencies are
changed by software using the frequency control register (FRQCR) setting.
The clock can be stopped in sleep mode and standby mode and specific modules can be
stopped using the module standby function.
If the clock supplied through the clock input pin stops for any reason, the timer pins can be
automatically placed in the high-impedance state.
