T contains measurements from the on-chip temperature sensor. Measurements are performed during continu-

ous conversions, with the default the Celsius scale (oC). The value is represented in two's complement notation

and in the range of -128.0 ≤ T < 128.0, with the binary point to the right of the eighth MSB.

PC2[7:0]

Phase compensation. Sets a delay in the voltage channel relative to current channel 2. Default

setting is 00000000 = 0.0215 degree phase delay at 60 Hz (when MCLK = 4.096 MHz).

Igain (I2gain)

Sets the gain of the current (current 2) PGA.

0 = Gain is 10 (default)

1 = Gain is 50

STOP

Terminates the auto-boot sequence.

0 = Normal (default)

1 = Stop sequence

INTOD

Converts INT output pin to an open drain output.

0 = Normal (default)

1 = Open drain

NOCPU

Saves power by disabling the CPUCLK pin.

0 = Normal (default)

1 = Disables CPUCLK

NOOSC

Saves power by disabling the crystal oscillator.

0 = Normal (default)

1 = Disabling oscillator circuit
