These three elements
are repeated for each
monitored message
Notes:
1. The Message Length Word indicates the number of bytes
stored in the Message Data Block. The range is 2 to 72 bytes,
corresponding to 1 to 36 16-bit words stored.
2. The Response Time Word contains two 8-bit fields:
For all messages except RT-to-RT, the GAP1 byte indicates the
only RT response time. For RT-to-RT, the GAP1 byte indicates
the Transmit RT response time, and the GAP2 byte indicates the
Receive RT response time. For both, the gap is measured from
mid-parity zero-crossing of the preceding word, to the mid-sync
zero-crossing of the Status Word. The gap time resolution is
100ns per LSB, so the maximum indicated gap time is 25.5
3. The high order Message Time Stamp Word (bits 63~48)
is always 0x0000.
