SWPMI Transmit/Receive functions.
===============================================================================
##### IO operation methods #####
===============================================================================
[..]
This subsection provides a set of functions allowing to manage the SWPMI
data transfers.
(#) There are two modes of transfer:
(++) Blocking mode: The communication is performed in polling mode.
The HAL status of all data processing is returned by the same function
after finishing transfer.
(++) Non-Blocking mode: The communication is performed using Interrupts
or DMA. The end of the data processing will be indicated through the
dedicated SWPMI Interrupt handler (HAL_SWPMI_IRQHandler()) when using Interrupt mode or
the selected DMA channel interrupt handler when using DMA mode.
The HAL_SWPMI_TxCpltCallback(), HAL_SWPMI_RxCpltCallback() user callbacks
will be executed respectively at the end of the transmit or receive process.
The HAL_SWPMI_ErrorCallback() user callback will be executed when a communication error is detected.
(#) Blocking mode API's are:
(++) HAL_SWPMI_Transmit()
(++) HAL_SWPMI_Receive()
(#) Non-Blocking mode API's with Interrupt are:
(++) HAL_SWPMI_Transmit_IT()
(++) HAL_SWPMI_Receive_IT()
(++) HAL_SWPMI_IRQHandler()
(#) Non-Blocking mode API's with DMA are:
(++) HAL_SWPMI_Transmit_DMA()
(++) HAL_SWPMI_Receive_DMA()
(++) HAL_SWPMI_DMAPause()
(++) HAL_SWPMI_DMAResume()
(++) HAL_SWPMI_DMAStop()
(#) A set of Transfer Complete Callbacks are provided in Non-Blocking mode:
(++) HAL_SWPMI_TxHalfCpltCallback()
(++) HAL_SWPMI_TxCpltCallback()
(++) HAL_SWPMI_RxHalfCpltCallback()
(++) HAL_SWPMI_RxCpltCallback()
(++) HAL_SWPMI_ErrorCallback()
(#) The capability to launch the above IO operations in loopback mode for
user application verification:
(++) HAL_SWPMI_EnableLoopback()
(++) HAL_SWPMI_DisableLoopback()
