bits (register 0x49). When EPRDIEN is logic one and EPRDISCR is logic one, the value
register 0x49 G1[1:0] is ignored and the EPRDI bits in the G1 byte are set according to the
setting of the Channel Auto Enhanced Path RDI Control registers (0x92 and 0x93).
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 zero, the basic path RDI scheme is used and
only G1[5] is used to indicate PRDI. When EPRDIEN is set to logic one, 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.
