Table 122. RX FIFO Port Reset ($0x59E)

Bit	Name	Description		Type1	Default
Register Description: The soft reset register for each port in the RX block. Port ID = bit
position in the register. To make the reset active, the bit must be set High. For example, reset					0x00000000
of port 1 implies register value = 0000_0018. Setting the bit to 0 de-asserts the reset.
