Description
Value used to determine the COP Filter Threshold. The clamp is sampled
every 20s and over the selected interval is compared to COP time-on
threshold, T_ON(th) to determine if an COP fault has occurred.
COP_THRES[6:0] ^{For a 1 second interval:}
TON_{th} = COP_THRES [6:0]  5.12ms  + 2.56ms
For a 2 second interval:
T_{ONth} = COP_THRES [6:0]  10.24ms  + 5.12ms
COP_INT
Configures the time interval to check for a boost stage COP fault.
0 = 1 second interval
1 = 2 second interval
