RTCC_PRSSel_TypeDef#

typedef uint8_t RTCC_PRSSel_TypeDef

This type is used when configuring input capture mode on a RTCC channel.

RTCC_ChannelCompareValueGet#

uint32_t RTCC_ChannelCompareValueGet (int ch)

Get the RTCC compare register value for a selected channel.

Returns

• Compare register value.

RTCC_ChannelCompareValueSet#

void RTCC_ChannelCompareValueSet (int ch, uint32_t value)

Set the RTCC compare register value for a selected channel.

RTCC_ChannelCaptureValueGet#

uint32_t RTCC_ChannelCaptureValueGet (int ch)

Get the RTCC input capture register value for a selected channel.

Returns

• Capture register value.

RTCC_ChannelCCVGet#

uint32_t RTCC_ChannelCCVGet (int ch)

Get the RTCC capture/compare register value for a selected channel.

For parts with separate capture compare value registers, this function returns the compare value.

Returns

• Capture/compare register value.

RTCC_ChannelCCVSet#

void RTCC_ChannelCCVSet (int ch, uint32_t value)

Set RTCC capture/compare register value for a selected channel.

For parts with separate capture compare value registers, this function sets the compare value.

RTCC_CombinedCounterGet#

uint32_t RTCC_CombinedCounterGet (void )

Get the combined CNT/PRECNT register content.

Returns

• CNT/PRECNT register value.

RTCC_CounterGet#

uint32_t RTCC_CounterGet (void )

Get the RTCC counter value.

Returns

• Current RTCC counter value.

RTCC_CounterSet#

void RTCC_CounterSet (uint32_t value)

Set the RTCC CNT counter.

RTCC_Enable#

void RTCC_Enable (bool enable)

Enable/disable RTCC counting.

RTCC_Init#

void RTCC_Init (const RTCC_Init_TypeDef * init)

Initialize RTCC.

Note that the compare values must be set separately with RTCC_CompareSet(), which should probably be done prior to the use of this function if configuring the RTCC to start when initialization is completed.

RTCC_ChannelInit#

void RTCC_ChannelInit (int ch, RTCC_CCChConf_TypeDef const * confPtr)

Configure the selected capture/compare channel of the RTCC.

Use this function to configure an RTCC channel. Select capture/compare mode, match output action, overflow output action, and PRS input configuration. See the configuration structure RTCC_CCChConf_TypeDef for more details.

RTCC_IntClear#

void RTCC_IntClear (uint32_t flags)

Clear one or more pending RTCC interrupts.

RTCC_IntDisable#

void RTCC_IntDisable (uint32_t flags)

Disable one or more RTCC interrupts.

RTCC_IntEnable#

void RTCC_IntEnable (uint32_t flags)

Enable one or more RTCC interrupts.

Note

• Depending on the use, a pending interrupt may already be set prior to enabling the interrupt. To ignore a pending interrupt, consider using RTCC_IntClear() prior to enabling the interrupt.

RTCC_IntGet#

uint32_t RTCC_IntGet (void )

Get pending RTCC interrupt flags.

Note

• Event bits are not cleared by using this function.

Returns

• Pending RTCC interrupt sources. Returns a set of interrupt flags OR-ed together for the interrupt sources set.

RTCC_IntGetEnabled#

uint32_t RTCC_IntGetEnabled (void )

Get enabled and pending RTCC interrupt flags.

Useful for handling more interrupt sources in the same interrupt handler.

Returns

• Pending and enabled RTCC interrupt sources. Returns a set of interrupt flags OR-ed together for the interrupt sources set.

RTCC_IntSet#

void RTCC_IntSet (uint32_t flags)

Set one or more pending RTCC interrupts from SW.

RTCC_Lock#

void RTCC_Lock (void )

Lock RTCC registers.

Note

• When RTCC registers are locked, RTCC_CTRL, RTCC_PRECNT, RTCC_CNT, RTCC_TIME, RTCC_DATE, RTCC_IEN, RTCC_POWERDOWN and RTCC_CCx_XXX registers cannot be written to.

RTCC_PreCounterGet#

uint32_t RTCC_PreCounterGet (void )

Get the RTCC pre-counter value.

Returns

• Current RTCC pre-counter value.

RTCC_PreCounterSet#

void RTCC_PreCounterSet (uint32_t preCntVal)

Set the RTCC pre-counter value.

RTCC_Reset#

void RTCC_Reset (void )

Restore RTCC to its reset state.

RTCC_StatusClear#

void RTCC_StatusClear (void )

Clear the STATUS register.

RTCC_StatusGet#

uint32_t RTCC_StatusGet (void )

Get the STATUS register value.

Returns

• Current STATUS register value.

RTCC_SyncWait#

void RTCC_SyncWait (void )

Wait for the RTCC to complete all synchronization of register changes and commands.

RTCC_Start#

void RTCC_Start (void )

Start the RTCC counter.

This function will send a start command to the RTCC peripheral. The RTCC peripheral will use some LF clock ticks before the command is executed. The RTCC_SyncWait() function can be used to wait for the start command to be executed.

Note

• This function requires the RTCC to be enabled.

RTCC_Stop#

void RTCC_Stop (void )

Stop the RTCC counter.

This function will send a stop command to the RTCC peripheral. The RTCC peripheral will use some LF clock ticks before the command is executed. The RTCC_SyncWait() function can be used to wait for the stop command to be executed.

Note

• This function requires the RTCC to be enabled.

RTCC_Unlock#

void RTCC_Unlock (void )

Unlock RTCC registers.

Note

• When RTCC registers are locked, RTCC_CTRL, RTCC_PRECNT, RTCC_CNT, RTCC_TIME, RTCC_DATE, RTCC_IEN, RTCC_POWERDOWN and RTCC_CCx_XXX registers cannot be written to.

RTCC_INIT_DEFAULT#

#define RTCC_INIT_DEFAULT

Default RTCC initialization structure.

RTCC_CH_INIT_COMPARE_DEFAULT#

#define RTCC_CH_INIT_COMPARE_DEFAULT

Default RTCC channel output compare initialization structure.

RTCC_CH_INIT_CAPTURE_DEFAULT#

#define RTCC_CH_INIT_CAPTURE_DEFAULT

RTCC_CH_VALID#

#define RTCC_CH_VALID

(ch)

Number of RTCC capture/compare channels.

Validation of valid RTCC channel for assert statements.
