12.1.5 CORRUPT_SHP_FRAMING
(Offset in the Register Area: 0x0124)
This command forces the link layer to send Header Packet with one invalid symbol in SHP framing
sequence. Any symbol of the framing sequence can be selected (using Bitmap field) to be replaced by
specified symbol (K and 8b fields). All the other details are just similar to Error! Reference source not

This bit shows that the error has been injected at least once
from the last time EN has been set. It will be cleared
whenever a value 1 is written to EN. RO

Number of times the error should be injected if the MODE is
1. When read, it shows number of times remained yet to
finish the requested count. RW
19:16 Bitmap
This field determines which symbols in the framing
sequence should be corrupted. Bit 16 corresponds to first
framing symbol in the sequence and bit 19 corresponds to
EPF. SW should always write a non-zero value into this
field, otherwise, it will not inject any error. RW
