OPRT data
Note:
This data displays when the IC Route number is larger than 63, and b6 of
displays as “1” (otherwise,
“1” displays at any time). While the six-bit data of is self-sufficient in verifying the Route 1-63, this OPRT
data provides a supportive role to cover Route number larger than 63. Use the following method to analyze
the data:
