Store VT/TU Pointer Location. This value indicates the
stored location of the V5 byte within the VT/TU mapping.
VT Pointer Decrement Count. VT pointer decrement
count updated on a 0 to 1 transition of
SMPR_PMRESET.
VT Pointer Increment Count. VT pointer increment
count updated on a 0 to 1 transition of
SMPR_PMRESET.
Reserved.
Transmit Elastic Store High Threshold. Programmable
threshold controlling positive justifications.
Reserved.
Transmit Elastic Store Low Threshold. Programmable
threshold controlling negative justifications.
J2 Expected Values. This value is programmed by the
user as an expected value for the J2 byte. The hardware
will compare this value to the incoming J2 sequence
when VT_J2MON_MODE[1—28][2:0] = 011 or 100
(Table 204 on pag
J2 Detected Values. Accepted J2 sequence or value.
