6.3.1 Peripherals in Low-Power Modes

Peripherals can be in different states that impact the achievable power modes of the device. The states depend on the operational modes of the peripherals (see Table 6-2). 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 and instead enters a power mode that still supports the current state of the peripherals, unless an external clock is used. If an external clock is used, the application must ensure that the correct frequency range for the requested power mode is selected.

(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 will cause a temporary transition into active mode for the time of the transfer.
(5) Operates only during active mode and will delay the transition into a low-power mode until its operation is completed.
