10. Low Power Consumption Controller (CPU intermittent operation function, stable oscillation
wait time, and clock multiplier function)
The following operation modes are available: PLL clock mode, PLL sleep mode, clock mode, main clock mode,
main sleep mode and stop mode. Operation modes other than PLL clock mode are classified as low power
consumption modes.
Main clock mode and main sleep mode are modes where the microcontroller operates using the main clock
(OSC oscillation clock) only. In these modes, the main clock divided by two is used as the operation clock and
the PLL clock (VCO oscillation clock) is stopped.
In PLL sleep mode and main sleep mode, only the operation clock of the CPU is stopped, while operations
besides the CPU clock continue.
In clock mode, only the timebase timer is allowed to operate.
In stop mode, oscillation is stopped, allowing data to be held at the lowest power consumption possible.
The CPU intermittent operation function causes the clock provided to the CPU to function intermittently when
accessing registers, internal memory, internal resources and the external bus. This allows processing to be
performed at lower power consumption by reducing the CPU execution speed while continuing to provide a high
speed clock to internal resources.
The PLL clock multiplier can be selected as 1, 2, 3 or 4 using the CS1 and CS0 bits.
The stable oscillation wait time for the main clock when stop mode is cancelled can be set using the WS1 and
WS0 bits.
