14.7.14 Resetting Transmit FIFO
A Transmit FIFO can be reset by:
Setting FRESET (CxFIFOCONx[10]) or
Placing the module in Configuration mode (OPMOD[2:0] = 100
).
Resetting the FIFO will reset the head and tail pointers and the CxFIFOSTAx register. The settings in the CxFIFOCONx register will not change.
Before resetting a TX FIFO using FRESET, ensure no transmissions are pending.
