(USART_HandleTypeDef * husart)
Function description
Abort ongoing transfer (Interrupt mode).
Parameters
husart: USART handle.
Return values
HAL: status
Notes
This procedure could be used for aborting any ongoing
transfer (either Tx or Rx, as described by TransferType
parameter) started in Interrupt or DMA mode. This procedure
performs following operations : Disable PPP Interrupts
(depending of transfer direction)Disable the DMA transfer in
the peripheral register (if enabled)Abort DMA transfer by
calling HAL_DMA_Abort_IT (in case of transfer in DMA
mode)Set handle State to READYAt abort completion, call
user abort complete callback
This procedure is executed in Interrupt mode, meaning that
abort procedure could be considered as completed only when
user abort complete callback is executed (not when exiting
function).

Parameters
husart: pointer to a USART_HandleTypeDef structure that
contains the configuration information for the specified
USART module.
Return values
None:
HAL_USART_TxHalfCpltCallback
Function name
void HAL_USART_TxHalfCpltCallback
(USART_HandleTypeDef * husart)
Function description
Tx Half Transfer completed callbacks.
Parameters
