G1[0]
This register allows control over the path status byte.
G1[1:0]:
The G1[1:0] bits are inserted in bits 1 and 2 of the Path Status Byte G1. These bits are
ignored when EPRDIEN is logic zero or when EPRDIEN and EPRDISRC are both logic one.
See the description of EPRDIEN and EPRDISRC for more details on how G1 can be
controlled.
APRDI:
The APRDI bit controls the insertion of the auxiliary path remote defect indication. When
APRDI is a logic one, the APRDI bit position in the path status byte is set high. When APRDI
is a logic zero, the APRDI bit position in the path status byte is set low.
PRDI:
The PRDI bit controls the insertion of the path remote defect indication. When a logic one is
written to this bit position, the PRDI bit position in the path status byte is set high. When a
logic zero is written to this bit position, the PRDI bit position in the path status byte is set low.
This bit is ignored when EPRDIEN is logic zero or when EPRDIEN and EPRDISRC are both
logic one.
FEBE[3:0]:
The FEBE[3:0] bits are inserted in the FEBE bit positions in the path status byte. The value
contained in FEBE[3:0] is cleared after being inserted in the path status byte. Any non-zero
FEBE[3:0] value overwrites the value that would normally have been inserted based on the
number of FEBEs accumulated on primary input FEBE during the last frame. When reading
this register, a non-zero value in these bit positions indicates that the insertion of this value is
still pending.
