Detailed Description

Get the enable or disable status of the APB2 peripheral clock during Low Power (Sleep) mode.

Note

Peripheral clock gating in SLEEP mode can be used to further reduce power consumption.

After wakeup from SLEEP mode, the peripheral clock is enabled again.

By default, all peripheral clocks are enabled during SLEEP mode.
