SerCx2SystemDmaTransmitCleanupTransactionComplete function (sercx.h)

  • Article

The SerCx2SystemDmaTransmitCleanupTransactionComplete method notifies version 2 of the serial framework extension (SerCx2) that the serial controller driver has finished cleaning up the serial controller's hardware state after a system-DMA-transmit transaction.

Syntax

void SerCx2SystemDmaTransmitCleanupTransactionComplete(
  [in] SERCX2SYSTEMDMATRANSMIT SystemDmaTransmit
);

Parameters

[in] SystemDmaTransmit

A SERCX2SYSTEMDMATRANSMIT handle to a system-DMA-transmit object. The serial controller driver previously called the SerCx2SystemDmaTransmitCreate method to create this object.

Return value

None

Remarks

After a system-DMA-transmit transaction ends, SerCx2 calls the EvtSerCx2SystemDmaTransmitCleanupTransaction event callback function, if it is implemented, to clean up the serial controller state. In response to this call, the driver should do any clean-up work that is needed; then the driver must call SerCx2SystemDmaTransmitCleanupTransactionComplete to notify SerCx2. SerCx2 expects this notification and does not start the next transaction until it is notified.

The serial controller driver must call SerCx2SystemDmaTransmitCleanupTransactionComplete only in response to a call to the EvtSerCx2SystemDmaTransmitCleanupTransaction function.
