6. REGISTER DESCRIPTION
1.
2.
“Default” = bit status after power-on or reset
Any bit not labeled is Reserved. A zero should always be used when writing to one of these bits.

Phase compensation. A 2’s complement number which sets a delay in the voltage channel rel-
ative to the current channel. Default setting is 0000000 = 0.0215 degree phase delay at 60 Hz
(when MCLK = 4.096 MHz). See Section 7.2 Phase Compensation on page 39 for more infor-
mation.
Sets the gain of the current PGA.
0 = Gain is 10 (default)
1 = Gain is 50
Allows the E1 and E2 pins to be configured as open-collector output pins.
0 = Normal outputs (default)
1 = Only the pull-down device of the E1 and E2 pins are active
Interrupt configuration bits. Select the desired pin behavior for indication of an interrupt.
00 = Active-low level (default)
01 = Active-high level
10 = High-to-low pulse
11 = Low-to-high pulse
Inverts the CPUCLK clock. In order to reduce the level of noise present when analog signals
are sampled, the logic driven by CPUCLK should not be active during the sample edge.
0 = Normal operation (default)
1 = Minimize noise when CPUCLK is driving rising edge logic
Clock divider. A 4-bit binary number used to divide the value of MCLK to generate the internal
clock DCLK. The internal clock frequency is DCLK = MCLK/K. The value of K can range be-
tween 1 and 16. Note that a value of “0000” will set K to 16 (not zero). K = 1 at reset.
