RXPRST:
The RXPRST bit is used to reset the RXPHY circuitry. When RXPRST is set to logic zero,
the RXPHY operates normally. When RXPRST is set to logic one, the RXPHY ignores all pin
inputs but the register bits may be accessed for purposes of initialization. The RXPHY
deasserts all outputs until a logic zero is written to RXPRST.
ODDPARITY:
The ODDPARITY bit is used to set the type of parity that is generated by the RXPHY for the
UL3 or POS L3 interface. When set to logic 1, odd parity is generated. When set to logic 0,
even parity is generated.
Reserved:
The Reserved bits must be set to logic 0 for proper operation.
