Functions

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

 Gets currently configured retiming option.

Detailed Description

EFR32-specific retiming capability.

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

Function Documentation

◆ RAIL_ConfigRetimeOptions()

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

Configure retiming options.

Parameters
[in]railHandleA handle of RAIL instance.
[in]maskA bitmask containing which options should be modified.
[in]optionsA 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 
)

Gets currently configured retiming option.

Parameters
[in]railHandleA handle of RAIL instance.
[out]pOptionsA pointer to configured retiming options bitmask indicating which are enabled.
Returns
Status code indicating success of the function call.
