2.75 Power, Clock and Reset (PCR) Module
The PCR module provides control of peripheral clocks, ability to reset peripherals and control of power to the peripherals.
Library Interface
PCR peripheral library provides the following interfaces:
Functions
| Name | Description |
|---|---|
| PCR_Initialize | Initializes the PCR module based on MCC configuration |
| PCR_PeripheralResetLock | Locks the peripheral reset enable register |
| PCR_PeripheralResetUnLock | Unlocks the peripheral reset enable register |
| PCR_PrivilegeEnLock | Locks privilege enable registers |
| PCR_PrivilegeEnUnLock | Un-locks privilege enable registers |
| PCR_PrivilegeDisablex | Enables access to the given peripheral block in all modes |
| PCR_PrivilegeEnablex | Enables access to the given peripheral block in all modes |
| PCR_ResetEnablex | Resets the given peripheral |
| PCR_SleepDisablex | Brings the module out of sleep mode and is free to use the clock as necessary |
| PCR_SleepEnablex | The given peripheral block is commanded to enter into sleep mode at the next available moment |
Data types and constants
| Name | Type | Description |
|---|---|---|
| PCR_SLEEP_ENx | Enum | This enum is used to specify the peripheral block for which sleep mode needs to be enabled/disabled using the PCR_SleepEnablex()/PCR_SleepDisablex() API |
| PCR_RESET_ENx | Enum | This enum is used to specify the peripheral block for which reset needs to be enabled using the PCR_ResetEnablex() API |
| PCR_PRIV_ENx | Enum | This enum is used to specify the peripheral block for which privilege access is to be enabled/disabled using the PCR_PrivilegeEnablex()/PCR_PrivilegeDisablex() API |
Note: Not all APIs maybe implemented. See the specific device family
section for available APIs.
