Function Documentation

◆ PRS_SourceSignalSet()

void PRS_SourceSignalSet	(	unsigned int	`ch,`
		uint32_t	`source,`
		uint32_t	`signal,`
		PRS_Edge_TypeDef	`edge`
	)

Set a source and signal for a channel.

Parameters

[in]	`ch`	A channel to define the signal and source for.
[in]	`source`	A source to select for the channel. Use one of PRS_CH_CTRL_SOURCESEL_x defines.
[in]	`signal`	A signal (for selected `source` ) to use. Use one of PRS_CH_CTRL_SIGSEL_x defines.
[in]	`edge`	An edge (for selected source/signal) to generate the pulse for.

◆ PRS_SourceAsyncSignalSet()

void PRS_SourceAsyncSignalSet	(	unsigned int	`ch,`
		uint32_t	`source,`
		uint32_t	`signal`
	)

Set the source and asynchronous signal for a channel.

Asynchronous reflexes are not clocked on HFPERCLK and can be used even in EM2/EM3. There is a limitation to reflexes operating in asynchronous mode in that they can only be used by a subset of the reflex consumers. See the PRS chapter in the reference manual for the complete list of supported asynchronous signals and consumers.

Note: This function is not supported on EFM32GxxxFyyy parts. In asynchronous mode, the edge detector only works in EM0 and should not be used. The EDSEL parameter in PRS_CHx_CTRL register is set to 0 (OFF) by default.

Parameters

[in]	`ch`	A channel to define the source and asynchronous signal for.
[in]	`source`	A source to select for the channel. Use one of PRS_CH_CTRL_SOURCESEL_x defines.
[in]	`signal`	An asynchronous signal (for selected `source` ) to use. Use one of the PRS_CH_CTRL_SIGSEL_x defines that support asynchronous operation.

◆ PRS_GpioOutputLocation()

void PRS_GpioOutputLocation	(	unsigned int	`ch,`
		unsigned int	`location`
	)

Send the output of a PRS channel to a GPIO pin.

This function is used to send the output of a PRS channel to a GPIO pin. Note that there are certain restrictions to where a PRS channel can be routed. Consult the datasheet of the device to see if a channel can be routed to the requested GPIO pin.

Parameters

[in]	`ch`	PRS channel number.
[in]	`location`	PRS routing location.

◆ PRS_GetFreeChannel()

int PRS_GetFreeChannel ( PRS_ChType_t type )

Search for the first free PRS channel.

Parameters

[in] type PRS channel type. This can be either prsTypeAsync or prsTypeSync .

Returns: Channel number >= 0 if an unused PRS channel was found. If no free PRS channel was found then -1 is returned.

◆ PRS_Reset()

void PRS_Reset ( void )

Reset all PRS channels.

This function will reset all the PRS channel configuration.

◆ PRS_ConnectSignal()

void PRS_ConnectSignal	(	unsigned int	`ch,`
		PRS_ChType_t	`type,`
		PRS_Signal_t	`signal`
	)

Connect a PRS signal to a channel.

This function will make the PRS signal available on the specific channel. Only a single PRS signal can be connected to any given channel.

Parameters

[in]	`ch`	PRS channel number.
[in]	`type`	PRS channel type. This can be either prsTypeAsync or prsTypeSync .
[in]	`signal`	This is the PRS signal that should be placed on the channel.

◆ PRS_LevelSet()

void PRS_LevelSet	(	uint32_t	`level,`
		uint32_t	`mask`
	)

inline

Set level control bit for one or more channels.

The level value for a channel is XORed with both the pulse possibly issued by PRS_PulseTrigger() and the PRS input signal selected for the channel(s).

Parameters

[in]	`level`	Level to use for channels indicated by `mask` . Use logical OR combination of PRS_SWLEVEL_CHnLEVEL defines for channels to set high level, otherwise 0.
[in]	`mask`	Mask indicating which channels to set level for. Use logical OR combination of PRS_SWLEVEL_CHnLEVEL defines.

◆ PRS_LevelGet()

uint32_t PRS_LevelGet ( void )

inline

Get level control bit for all channels.

Returns: The current software level configuration.

◆ PRS_Values()

uint32_t PRS_Values ( PRS_ChType_t type )

inline

Get the PRS channel values for all channels.

Parameters

[in] type PRS channel type. This can be either prsTypeAsync or prsTypeSync .

Returns: The current PRS channel output values for all channels as a bitset.

◆ PRS_ChannelValue()

bool PRS_ChannelValue	(	unsigned int	`ch,`
		PRS_ChType_t	`type`
	)

inline

Get the PRS channel value for a single channel.

Parameters

[in]	`ch`	PRS channel number.
[in]	`type`	PRS channel type. This can be either prsTypeAsync or prsTypeSync .

Returns: The current PRS channel output value. This is either 0 or 1.

◆ PRS_PulseTrigger()

void PRS_PulseTrigger ( uint32_t channels )

inline

Trigger a high pulse (one HFPERCLK) for one or more channels.

Setting a bit for a channel causes the bit in the register to remain high for one HFPERCLK cycle. Pulse is XORed with both the corresponding bit in PRS SWLEVEL register and the PRS input signal selected for the channel(s).

Parameters

[in] channels Logical ORed combination of channels to trigger a pulse for. Use PRS_SWPULSE_CHnPULSE defines.

◆ PRS_ChannelLevelSet()

void PRS_ChannelLevelSet	(	unsigned int	`ch,`
		bool	`level`
	)

inline

Set the PRS channel level for one asynchronous PRS channel.

Parameters

[in]	`ch`	PRS channel number.
[in]	`level`	true to set the level high (1) and false to set the level low (0).

◆ PRS_ChannelPulse()

void PRS_ChannelPulse ( unsigned int ch )

inline

Trigger a pulse on one PRS channel.

Parameters

[in] ch PRS channel number.
