This register specifies the fraction of full-scale current that causes the MAXQ3181 to switch from PA0 to PA1 to pro-
vide phase-angle compensation. For more information, see the PA0, PA1, and PA2 register descriptions. The full-
scale current is represented by 0x10000.
This register specifies the fraction of full-scale current that causes the MAXQ3181 to switch from PA1 to PA2 to pro-
vide phase-angle compensation. For more information, see the PA0, PA1, and PA2 register descriptions. The full-
scale current is represented by 0x10000.
This register contains gain compensation coefficient for the neutral current channel measurement. The raw values
are taken from the selected measurement quantity and scaled by N.I_GAIN/2
