SERCX2_PIO_TRANSMIT_CONFIG structure (sercx.h)
The SERCX2_PIO_TRANSMIT_CONFIG structure contains information that version 2 of the serial framework extension (SerCx2) uses to configure a new PIO-transmit object.

Members
Size
The size, in bytes, of this structure. The SerCx2PioTransmitCreate method uses this member to determine which version of the structure the caller is using. The size of this structure might change in future versions of the Sercx.h header file.
EvtSerCx2PioTransmitInitializeTransaction
A pointer to the driver-implemented EvtSerCx2PioTransmitInitializeTransaction event callback function. This member must point to a valid function.
EvtSerCx2PioTransmitCleanupTransaction
A pointer to the driver-implemented EvtSerCx2PioTransmitCleanupTransaction event callback function. This member must point to a valid function.
EvtSerCx2PioTransmitWriteBuffer
A pointer to the driver-implemented EvtSerCx2PioTransmitWriteBuffer event callback function. This member must point to a valid function.
EvtSerCx2PioTransmitEnableReadyNotification
A pointer to the driver-implemented EvtSerCx2PioTransmitEnableReadyNotification event callback function. This member must point to a valid function.
EvtSerCx2PioTransmitCancelReadyNotification
A pointer to the driver-implemented EvtSerCx2PioTransmitCancelReadyNotification event callback function. This member must point to a valid function.
EvtSerCx2PioTransmitDrainFifo
A pointer to the driver-implemented EvtSerCx2PioTransmitDrainFifo event callback function. This member is optional and can be set to NULL to indicate that the driver does not implement the function. However, a driver that implements this function must also implement EvtSerCx2PioTransmitCancelDrainFifo and EvtSerCx2PioTransmitPurgeFifo functions.
EvtSerCx2PioTransmitCancelDrainFifo
A pointer to the driver-implemented EvtSerCx2PioTransmitCancelDrainFifo event callback function. This member is optional and can be set to NULL to indicate that the driver does not implement the function. However, a driver that implements this function must also implement EvtSerCx2PioTransmitDrainFifo and EvtSerCx2PioTransmitPurgeFifo functions.
EvtSerCx2PioTransmitPurgeFifo
A pointer to the driver-implemented EvtSerCx2PioTransmitPurgeFifo event callback function. This member is optional and can be set to NULL to indicate that the driver does not implement the function. However, a driver that implements this function must also implement EvtSerCx2PioTransmitDrainFifo and EvtSerCx2PioTransmitCancelDrainFifo functions.
Remarks
The SerCx2PioTransmitCreate method accepts a pointer to a SERCX2_PIO_TRANSMIT_CONFIG structure as an input parameter. Before calling SerCx2PioTransmitCreate, call the SERCX2_PIO_TRANSMIT_CONFIG_INIT function to initialize this structure.
