This register allows control over the path status byte.
G[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 and the PRDI bit in the G1 byte (bit 6) is set according to the setting of the Channel Auto Enhanced Path RDI Control registers (0x92 and 0x93).
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
