◆ SSC_EnableInterrupts()

void SSC_EnableInterrupts ( Ssc ssc,
uint32_t  sources 
)

Enables one or more interrupt sources of a SSC peripheral.

Parameters
sscPointer to an SSC instance.
sourcesBitwise OR of selected interrupt sources.

◆ SSC_EnableReceiver()

void SSC_EnableReceiver ( Ssc ssc)

Enables the receiver of a SSC peripheral.

Parameters
sscPointer to an SSC instance.

◆ SSC_EnableTransmitter()

Enables the transmitter of a SSC peripheral.

Parameters
sscPointer to an SSC instance.

◆ SSC_IsRxReady()

uint8_t SSC_IsRxReady ( Ssc ssc)

Return 1 if one frame is received, 0 otherwise.

Parameters
sscPointer to an SSC instance.

◆ SSC_Read()

uint32_t SSC_Read ( Ssc ssc)
