Enabling the unused peripherals in the active period of the MCU increases its power consumption. In the applications, it is recommended to shut down unused peripherals by disabling its clock signal. This is possible by using appropriate power reduction register (PRR) available in the device, which disconnects the individual peripherals from peripheral clock domain. In Power-save and Power-down modes the modules are stopped regardless of the state of the PRRs since the peripheral clock domain is disabled.
Disable unused peripherals in the active period of the MCU to reduce the power consumed.
