QNSEL

CFP Pulse Output Source Select. This five-bit field determines what meter value will be accumulated in

each of the phases to produce the CFP pulse output. All other values are reserved.

00000 = Net real energy

00001 = Absolute real energy

00010 = Net reactive energy

00011 = Absolute reactive energy

00100 = Apparent energy

00110 = IRMS

00111 = VRMS

01000 = Real energy delivered to load

01001 = Real energy delivered to line

01010 = Reactive energy, quadrant I

01011 = Reactive energy, quadrant II

01100 = Reactive energy, quadrant III

01101 = Reactive energy, quadrant IV

PHASEC

CFP Phase C Inclusion. When this bit is set, phase C is included in CFP pulse generation.

PHASEB

CFP Phase B Inclusion. When this bit is set, phase B is included in CFP pulse generation.

PHASEA

CFP Phase A Inclusion. When this bit is set, phase A is included in CFP pulse generation.
