EPRDIEN
The enhanced path receive defect indication alarm enable bit (EPRDIEN)
controls the use of 3-bit RDI mode. When EPRDIEN is set to logic 0, the basic
path RDI scheme is used and only G1[5] is used to indicate PRDI. When
EPRDIEN is set to logic 1, the enhanced path RDI scheme is used and the
three G1[7:5] bits are used to indicate PRDI. The actual three bit code will be
controlled according to the EPRDISRC.
Reserved:
The reserved bits must be programmed to logic zero for proper operation.
