Detailed Description

Enable or disable 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 wake-up from SLEEP mode, the peripheral clock is enabled again.
By default, all peripheral clocks are enabled during SLEEP mode.
