PLconstH[15:0]
The PLconstH[15:0] and PLconstL[15:0] bits are high word and low word of PL_Constant respectively.
PL_Constant is a constant which is proportional to the sampling ratios of voltage and current, and inversely proportional to the
Meter Constant. PL_Constant is a threshold for energy calculated inside the chip, i.e., energy larger than PL_Constant will be
accumulated as 0.01CFx in the corresponding energy registers and then output on CFx if one CF reaches.
It is suggested to set PL_constant as a multiple of 4 so as to double or redouble Meter Constant in low current state to save ver-
ification time.
