10.4.3.1
10.4.3.2
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 VCC1 and VCC2 pins is VRAM or more, the internal
RAM is retained. When applying 2.7 or less voltage to VCC1 and VCC2 pins, make sure VCC1 ≥ VCC2 ≥
VRAM.
However, the peripheral functions clocked by external signals keep operating. The following interrupts can be
used to exit stop mode. Table 10.6 lists Interrupts to Stop Mode and Use Conditions
The microcomputer 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 disable).
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 10.7 lists Pin Status in Stop Mode.
