XMEGA E5 [DATASHEET]

12.3.3 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. Low

power mode option of 8MHz internal oscillator enables instant oscillator wake-up time. This reduces the MCU wake-up

time or enables the MCU wake-up from UART bus.

12.3.4 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. The low power option of 8MHz

internal oscillator can be enabled to further reduce the power consumption.

12.3.5 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. The low power option of

8MHz internal oscillator can be enabled to further reduce the power consumption.
