Function

POS-PHY Receive End Of Packet

Active high signal used to delineate the

packet boundaries on the RDAT bus.

When REOP is high, the end of the packet

is present on the RDAT bus.

Note that RMOD[1:0] indicates the number

of valid bytes the last double word is

composed of when REOP and RVAL are

asserted.

REOP is required to be present at the end

of every packet and is considered valid

only when RVAL is asserted.

REOP is updated on the rising edge of

RFCLK.

POS-PHY Receive error indicator

Active high signal used to indicate that the

current packet is aborted and should be

discarded. RERR shall only be asserted

when REOP and RVAL are asserted.

Conditions that can cause RERR to be set

may be, but are not limited to, FIFO

overflow, abort sequence detection and

FCS error.

RERR is updated on the rising edge of

RFCLK.
