Bit 0: Receive FIFO Reset (RFRST) – When 0, the Receive FIFO will resume normal operations, however, data is
discarded until a start of packet/cell is received after RAM power-up is completed. When 1, the Receive FIFO is
emptied, any transfer in progress is halted, the FIFO RAM is powered down, the associated RDXA signal is forced
low, and all incoming data is discarded. If the port was selected when the reset was initiated, the port will be
deselected, and must be reselected (REN) deasserted with address on RADR or RSX asserted with address on
RDATA) before any transfer will occur.
