E1 PRGD Shift Register Length (072H)
E1 PRGD Tap Bit Type Function Default (073H)
equal to the value of ‘PT[4:0] + 1’. In application, the PT is always less than the PL.
E1 PRGD Error Insertion (074H)
EVENT:
set from ‘0’ to ‘1’ again.
EIR[2:0]:
to another non-zero value, it is recommended to set the EIR[2:0] to ‘000’ first, then set the EIR[2:0] to the desired value.

These bits determine the length of the valid data in the PRGD pattern insertion register. The length is equal to the value of ‘PL[4:0] + 1’.
These bits determine the feedback tap position of the generated pseudo random pattern before it is transmitted. The feedback tap position is
A single bit error is generated when the state of this bit is changed from ‘0’ to ‘1’. To insert another bit error, this bit must be cleared to ‘0’, and then
The EIR[2:0] bits determine the bit error rate that will be inserted in the PRGD test pattern. If the bit error rate is changed from one non-zero value
