71M6511/71M6511H Demo Board User’s Manual
For each element, if ISQSUM of that element exceeds I CREEP_THR ,
the sample values for that element are not zeroed. Otherwise, the
accumulators for Wh, VARh, and VAh are not updated and the
0x13
61
ICREEP_THR
instantaneous value of IRMS for that element is zeroed.
LSB = 6.6952*10 -13 MAX 2 Wh
The default value 61 is equivalent to 80mA.
Demo Code revision 3.05: WCREEP_THR applies to phase A only.
