Power-down Mode
Power-save Mode
Standby Mode
Extended Standby 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.
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.
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.
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.
