10.3.2

Power-down Mode

In power-down mode, all clocks, including the real-time counter clock source, are stopped. This

allows operation only of asynchronous modules that do not require a running clock. The only

interrupts that can wake up the MCU are the two-wire interface address match interrupt, and

asynchronous port interrupts.

10.3.3

Power-save Mode

Power-save mode is identical to power down, with one exception. If the real-time counter (RTC)

is enabled, it will keep running during sleep, and the device can also wake up from either an

RTC overflow or compare match interrupt.

10.3.4

Standby Mode

Standby mode is identical to power down, with the exception that the enabled system clock

sources are kept running while the CPU, peripheral, and RTC clocks are stopped. This reduces

the wake-up time.

10.3.5

Extended Standby Mode

Extended standby mode is identical to power-save mode, with the exception that the enabled

system clock sources are kept running while the CPU and peripheral clocks are stopped. This

reduces the wake-up time.
