Description

Peripheral Reflex System (PRS) Peripheral API.

This module contains functions to control the PRS peripheral of Silicon Labs 32-bit MCUs and SoCs. The PRS allows configurable, fast, and autonomous communication between peripherals on the MCU or SoC.

Functions
void	PRS_SourceSignalSet (unsigned int ch, uint32_t source, uint32_t signal, PRS_Edge_TypeDef edge)
	Set a source and signal for a channel.

void	PRS_SourceAsyncSignalSet (unsigned int ch, uint32_t source, uint32_t signal)
	Set the source and asynchronous signal for a channel.

void	PRS_GpioOutputLocation (unsigned int ch, unsigned int location)
	Send the output of a PRS channel to a GPIO pin.

int	PRS_GetFreeChannel ( PRS_ChType_t type)
	Search for the first free PRS channel.

void	PRS_Reset (void)
	Reset all PRS channels.

void	PRS_ConnectSignal (unsigned int ch, PRS_ChType_t type, PRS_Signal_t signal)
	Connect a PRS signal to a channel.

void	PRS_LevelSet (uint32_t level, uint32_t mask)
	Set level control bit for one or more channels.

uint32_t	PRS_LevelGet (void)
	Get level control bit for all channels.

void	PRS_PulseTrigger (uint32_t channels)
	Trigger a high pulse (one HFPERCLK) for one or more channels.

void	PRS_ChannelLevelSet (unsigned int ch, bool level)
	Set the PRS channel level for one asynchronous PRS channel.

void	PRS_ChannelPulse (unsigned int ch)
	Trigger a pulse on one PRS channel.

Macros
#define	PRS_SYNC_CHAN_COUNT PRS_CHAN_COUNT
	PRS Synchronous channel count.

#define	PRS_ASYNC_CHAN_COUNT PRS_CHAN_COUNT
	PRS Asynchronous channel count.

#define	PRS_ASYNC_SUPPORTED 1
	PRS asynchronous support.

Enumerations
enum	PRS_ChType_t { prsTypeAsync , prsTypeSync }
	PRS Channel type.

enum	PRS_Edge_TypeDef { prsEdgeOff , prsEdgePos , prsEdgeNeg , prsEdgeBoth }
	Edge detection type.
