* Must be called periodically if any STM32 UART is configured for DMA.
|
|
* The DMA callback is triggered for each fifo size/2 bytes, but this can
|
|
* result in some bytes being transferred but not collected if the incoming
|
|
* data is not a whole multiple of half the FIFO size.
|
|
*
|
|
* May be safely called from either interrupt or thread context.
