Low-Power, Multifunction, Polyphase AFE
This register designates the threshold of the CFQ pulse. This value is used to set the meter constant for the CFQ
pulse output. When the CFQ pulse accumulator exceeds the value set in this register, the CFQ pulse output is acti-
vated and the CFQ pulse accumulator is reduced by the amount in this register.
This register contains gain coefficient for phase X current channel. The raw values are taken from the selected mea-
surement quantity and scaled by the factor:
Note: Bit 15 of this register must be set to zero for correct operation.
