9.5.1 Peripherals in Low-Power Modes

Peripherals can be in different states that affect the achievable power modes of the device. The states depend on the operational modes of the peripherals (see Table 9-2). The states are:

A peripheral is in a "high-frequency state" if it requires or uses a clock with a "high" frequency of more than 50 kHz.
A peripheral is in a "low-frequency state" if it requires or uses a clock with a "low" frequency of 50 kHz or less.
A peripheral is in an "unclocked state" if it does not require or use an internal clock.

If the CPU requests a power mode that does not support the current state of all active peripherals, the device does not enter the requested power mode, but it does enter a power mode that still supports the current state of the peripherals, except if an external clock is used. If an external clock is used, the application must use the correct frequency range for the requested power mode.

(1) Peripherals are in a state that requires or uses a clock with a "high" frequency of more than 50 kHz

(2) Peripherals are in a state that requires or uses a clock with a "low" frequency of 50 kHz or less.

(3) Peripherals are in a state that does not require or does not use an internal clock.

(4) The DMA always transfers data in active mode but can wait for a trigger in any low-power mode. A DMA trigger during a low-power mode causes a temporary transition into active mode for the time of the transfer.

(5) This peripheral operates during active mode only and will delay the transition into a low-power mode until its operation is completed.
