CPTR[9:0]:
The CPTR[9:0] bits in the THPP Current Pointer Register reflect the value of the current
payload pointer being inserted. This field can be used to verify the user programmable
pointer when FIXPTR is logic one.
S[1:0]:
The S[1:0] bits in the THPP Current Pointer Register reflect the ss bits being inserted. This
field can be used by the to verify the ss field in the user programmable pointer when FIXPTR
is logic one.
NDF[3:0]:
The NDF[3:0] bits in the THPP Current Pointer Register reflect the NDF bit field being
inserted. This field can be used to verify the NDF field in the user programmable pointer
when FIXPTR is logic one.
