1.1.7 Power, Clock and Reset (PCR) module
The PCR module provides control of peripheral clocks, ability to reset peripherals and control of power to the periperhals
Library Interface
PCR library provides the following interfaces:
Functions
| Name | Description |
|---|---|
| void PCR_Initialize (void | Initializes the PCR module based on MCC configuration |
| void PCR_PeripheralResetLock (void) | Locks the peripheral reset enable register |
| void PCR_PeripheralResetUnLock (void) | Unlocks the peripheral reset enable register |
| void PCR_PrivilegeEnLock (void) | Locks privilege enable registers |
| void PCR_PrivilegeEnUnLock (void) | Un-locks privilege enable registers |
| void PCR_PrivilegeDisablex (PCR_PRIV_ENx blockId) | Enables access to the given peripheral block in all modes |
| void PCR_PrivilegeEnablex (PCR_PRIV_ENx blockId) | Enables access to the given peripheral block in all modes |
| void PCR_ResetEnablex (PCR_RESET_ENx blockId) | Resets the given peripheral |
| void PCR_SleepDisablex (PCR_SLEEP_ENx blockId) | Brings the module out of sleep mode and is free to use the clock as necessary |
| void PCR_SleepEnablex (PCR_SLEEP_ENx blockId) | 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 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 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 to specify the peripheral block for which privilege access is to be enabled/disabled using the PCR_PrivilegeEnablex()/PCR_PrivilegeDisablex() API |
