REG_CSUM_OFF Disable checksum on critical registers.
0 = Enable checksum on critical registers (Default)
1 = Disable checksum on critical registers
AFC Enables automatic line frequency measurement which sets Epsilon every time a new
line frequency measurement completes. Epsilon is used to control the gain of
90-degree phase shift integrator used in quadrature power calculations.
0 = Disable automatic line frequency measurement
1 = Enable automatic line frequency measurement (Default)
I2FLT[1:0] Filter enable for current channel 2.
00 = No filter (Default)
01 = High-pass filter (HPF) on current channel 2
10 = Phase-matching filter (PMF) on current channel 2
11 = Rogowski coil integrator (INT) on current channel 2
V2FLT[1:0] Filter enable for voltage channel 2.
00 = No filter (Default)
01 = High-pass filter (HPF) on voltage channel 2
10 = Phase-matching filter (PMF) on voltage channel 2
11 = Reserved
I1FLT[1:0] Filter enable for current channel 1.
00 = No filter (Default)
01 = High-pass filter (HPF) on current channel 1
10 = Phase-matching filter (PMF) on current channel 1
11 = Rogowski coil integrator (INT) on current channel 1
V1FLT[1:0] Filter enable for voltage channel 1.
00 = No filter (Default)
01 = High-pass filter (HPF) on voltage channel 1
10 = Phase-matching filter (PMF) on voltage channel 1
11 = Reserved
IIR_OFF Bypass IIR filter.
0 = Do not bypass IIR filter (Default)
1 = Bypass IIR filter
