SAG_CNT
80
(0x50)
Number of consecutive voltage samples below SAG_THR before a sag
alarm is declared. The maximum value is 255. SAG_THR is at address
0x14.
[7] -- 0 Unused
[6]
FREQSEL
0 Selected phase for frequency monitor (0 = A, 1 = B).
[5]
EXT_PULSE
1
When zero, causes the pulse generators to respond to WSUM_X and
VARSUM_X. Otherwise, the generators respond to values the MPU places
in APULSEW and APULSER.
[4] -- 0 Unused
[3]
IB_SHUNT
0
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.
[2]
IA_SHUNT
0 When 1, the current gain of channel A is increased by 8.
[1]
PULSE_FAST
0
When PULSE_SLOW = 1, the pulse generator input is reduced by a factor of
64. When PULSE_FAST = 1, the pulse generator input is increased 16x.
These two parameters control the pulse gain factor X (see table below).
Allowed values are either 1 or 0. Default is 0 (X = 6).

CE TRANSFER VARIABLES
When the MPU receives the XFER_BUSY interrupt, it knows that fresh data is available in the transfer variables. The
transfer variables can be categorized as:
1. Fundamental energy measurement variables
2. Instantaneous (RMS) values
3. Other measurement parameters
4. Pulse generation variables
5. Current shunt variables
6. Calibration parameters
