RFPO/RMFPO[4:1] is valid when the
S/UNI-QJET is configured to be in framer
only mode. The 8KREFO bit must be set
to logic 0 S/UNI-QJET Configuration
Register.
RFPO[4:1] is aligned to RDATO[4:1] and
indicates the position of the first bit in each
DS3 M-subframe, the first bit in each
G.751 E3 or G.832 E3 frame, or the first
framing bit in each J2 frame
RMFPO[4]
RMFPO[3]
RMFPO[2]
RMFPO[1]
RMFPO[4:1] is aligned to RDATO[4:1] and
indicates the position of the first bit in each
DS3 M-frame, the first bit in each G.751 or
G.832 E3 multiframe, or the first framing
bit in each J2 multiframe.
RFPO/RMFPO[4:1] is updated on either
the falling or rising edge of RSCLK[4:1]
depending on the setting of the RSCLKR
bit in the S/UNI-QJET Receive
Configuration register.

Receive PLCP Overhead Data
(RPOH[4:1]). RPOH[4:1] contains the
PLCP path overhead octets (Zn, F1, B1,
G1, M1, M2, and C1) extracted from the
received PLCP frame when the PLCP
layer is in-frame. When the PLCP layer is
in the loss of frame state, RPOH[4:1] is
forced to all ones. The octet data on
RPOH[4:1] is shifted out in order from the
most significant bit (bit 1) to the least
significant bit (bit 8). RPOH[4:1] is
updated on the falling edge of
V10
