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 = I
00111 = V
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
CFP Phase C Inclusion. When this bit is set, phase C is included in CFP pulse generation.
CFP Phase B Inclusion. When this bit is set, phase B is included in CFP pulse generation.
CFP Phase A Inclusion. When this bit is set, phase A is included in CFP pulse generation.
