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.
