uint8_t *pData,
uint16_t Size);

Return value
HAL status
Notes
Reception is initiated by this function call. Further progress of reception is achieved thanks to DMA services, transferring automatically received data elements in user reception buffer and calling registered callbacks at half/end of reception. UART IDLE events are also used to consider reception phase as ended. In all cases, callback execution will indicate number of received data elements. When the UART parity is enabled (PCE = 1), the received data contain the parity bit (MSB position). When UART parity is not enabled (PCE = 0), and Word Length is configured to 9 bits (M = 01), the received data is handled as a set of uint16_t. In this case, Size must indicate the number of uint16_t available through pData.
