Functions
RAIL_Status_t	RAIL_ConfigRetimeOptions ( RAIL_Handle_t railHandle, RAIL_RetimeOptions_t mask, RAIL_RetimeOptions_t options)
	Configure retiming options.

RAIL_Status_t	RAIL_GetRetimeOptions ( RAIL_Handle_t railHandle, RAIL_RetimeOptions_t *pOptions)

Detailed Description

EFR32-specific retiming capability.

The EFR product families have many digital and analog modules that can run in parallel with a radio. These combinations can cause interference and degradation on the radio RX sensitivity. Retiming can modify the clocking of the digital modules to reduce the interference.

Function Documentation

◆ RAIL_ChangedDcdc()

RAIL_Status_t RAIL_ChangedDcdc ( void )

Indicate that the DCDC peripheral bus clock enable has changed allowing RAIL to react accordingly.

Note: This should be called after DCDC has been enabled or disabled.

Returns: Status code indicating success of the function call.

◆ RAIL_ConfigRetimeOptions()

RAIL_Status_t RAIL_ConfigRetimeOptions	(	RAIL_Handle_t	`railHandle,`
		RAIL_RetimeOptions_t	`mask,`
		RAIL_RetimeOptions_t	`options`
	)

Configure retiming options.

Parameters

[in]	`railHandle`	A handle of RAIL instance.
[in]	`mask`	A bitmask containing which options should be modified.
[in]	`options`	A bitmask containing desired configuration settings. Bit positions for each option are found in the RAIL_RetimeOptions_t .

Returns: Status code indicating success of the function call.

◆ RAIL_GetRetimeOptions()

RAIL_Status_t RAIL_GetRetimeOptions	(	RAIL_Handle_t	`railHandle,`
		RAIL_RetimeOptions_t *	`pOptions`
	)

Get the currently configured retiming option.

Parameters

[in]	`railHandle`	A handle of RAIL instance.
[out]	`pOptions`	A pointer to configured retiming options bitmask indicating which are enabled.

Returns: Status code indicating success of the function call.
