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, asyn-
chronous port interrupts, and the USB resume interrupt.
Power-save mode is identical to power down, with two exceptions:
1. If the real-time counter (RTC) is enabled, it will keep running during sleep, and the device
2. If the liquid crystal display controller (LCD) is enabled, it will keep running during sleep,
Standby mode is identical to power down, with the exception that the enabled system clock
sources are kept running while the CPU, peripheral, RTC and LCD 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.
can also wake up from either an RTC overflow or compare match interrupt.
and the device can wake up from LCD frame completed interrupt.
