Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

LDM_T4
|
LDM_T4 This is the 't4' timestamp, which is the time the link receives the LMP TS response. The unit of this field is nanosecond (ns). Note: - The internal RTL timer counts down 125000 to 0, and restarts at 125000 (therefore, t1 > t4, except the case of roll over) - This value does not take into account the internal RTL RX pipeline delay. RTL uses this formula for adjusting 't4' based on the pipeline delay: RX_PATH_DELAY(tIsochTimestampGranularity) = (gen1 ? 4 : 5) + LPTMDPDELAY[7:4] |
