8.4.3 Stop Mode
In stop mode, all oscillator circuits are turned off, so are the CPU clock and the peripheral function clocks.
Therefore, the CPU and the peripheral functions clocked by these clocks stop operating. The least
amount of power is consumed in this mode. If the voltage applied to VCC pin is VRAM or more, the
internal RAM is retained.
However, the peripheral functions clocked by external signals keep operating.
Table 8.6 lists the Interrupts to Stop Mode and Use Conditions.
8.4.3.1 Entering Stop Mode
8.4.3.2 Pin Status in Stop Mode
The MCU is placed into stop mode by setting the CM10 bit in the CM1 register to 1 (all clocks turned off).
At the same time, the CM06 bit in the CM0 register is set to 1 (divide-by-8 mode) and the CM15 bit in the
CM1 register is set to 1 (main clock oscillator circuit drive capability high).
Before entering stop mode, set the CM20 bit in the CM2 register to 0 (oscillation stop, re-oscillation
detection function disabled).
Also, if the CM11 bit in the CM1 register is 1 (PLL clock for the CPU clock source), set the CM11 bit to 0
(main clock for the CPU clock source) and the PLC07 bit in the PLC0 register to 0 (PLL turned off) before
entering stop mode.
Table 8.7 lists the Pin Status in Stop Mode.
