Sets the sag control of phase B.
Sets the sag control of phase A.
If more than one sag mask is set, a sag interrupt will only be
generated when all phases enabled for the interrupt sag.
When set, enables the sag interrupt to be output on the
YPULSE/DIO9 pin.
When set, enables the control of GAIN_ADJ by the MPU.
When 0, enables the control of GAIN_ADJ by the CE.
The number of consecutive voltage samples below SAG_THR
before a sag alarm is declared. The maximum value is 255.
SAG_THR is at address 0x24.
The combination of FREQSEL1 and FREQSEL0 selects the phase
to be used for the frequency monitor, the phase-to-phase lag
calculation, the zero-crossing counter MAINEDGE_X and the
F0 bit (CESTATUS[28]).
FREQSEL1/FREQSEL0 = 0/0: Phase A
FREQSEL1/FREQSEL0 = 0/1: Phase B
When zero, causes the pulse generators to respond to internal
data (PULSE0 = WSUM_X, PULSE1 = VARSUM_X., PULSE2 =
VASUM_X). Otherwise, the generators respond to values the
MPU places in APULSEW and APULSER.
Unused.
When 1, the current gain of channel B is increased by 8. The
gain factor controlled by In_SHUNT is referred to as In_8
throughout this document.
When 1, the current gain of channel A is increased by 8.
When PULSE_FAST = 1, the pulse generator input is increased
16x. When PULSE_SLOW = 1, the pulse generator input is
reduced by a factor of 64. These two bits control the pulse
gain factor X (see table below). Default is 0 for both (X = 6).

Table 59: Sag Threshold Control
Default
Description
The threshold for sag warnings. The default value is
443000 equivalent to 80 V RMS if VMAX = 600 V. The LSB value
is VMAX * 4.255*10^-7 V (peak).
