SPI underflow event may not generate if read/write to TXFIFO happen at the same time
In UNICOMMSPI-TXFIFO, underflow event will not get generated during a critical window when the bellow conditions happen together: 1. CPU/DMA write data into TXFIFO 2. SPI peripheral read TXFIFO to send data Not suggest to use underflow event function. User must ensure that the TXFIFO of UNICOMMSPI can never be empty when CPU/DMA access the TXFIFO.
