13. Low power consumption operation
STOP mode: Oscillation stops. (Battery/Capacitor back-up.)
SLOW1 mode: Low power consumption operation using low-frequency clock.(High- frequency clock stop.)
SLOW2 mode: Low power consumption operation using low-frequency clock.(High- frequency clock oscillate.)
IDLE0 mode: CPU stops, and only the Time-Based-Timer(TBT) on peripherals operate using high frequency clock. Release by falling edge of the source clock which is set by TBTCR.
IDLE1 mode: CPU stops and peripherals operate using high frequency clock. Release by interruputs(CPU restarts).
IDLE2 mode: CPU stops and peripherals operate using high and low frequency clock. Release by interruputs. (CPU restarts).
SLEEP0 mode: CPU stops, and only the Time-Based-Timer(TBT) on peripherals operate using low frequency clock.Release by falling edge of the source clock which is set by TBTCR.
SLEEP1 mode: CPU stops, and peripherals operate using low frequency clock. Release by interruput.(CPU restarts).
SLEEP2 mode: CPU stops and peripherals operate using high and low frequency clock. Release by interruput.
