CESTATE 0E 5005h
SAG CNT
Bits 15:8 –
determines the
consecutive voltage
samples below
SAG_Threshold
before a sag alarm
is declared. 255 is
the maximum
value.
Pulse Selection
(PULSEL)
Bit 4
0 – chooses Outlet
1 (IA input) for
pulse generation
1 – chooses Outlet
2 (IB input) for
pulse generation.
Reserved
Bit 3
Voltage Sensor
Configuration
Bit 2
0 – Isolated mode
uses VA-VB for
Voltage
1 – Non-isolated
mode uses VA for
voltage; V3P3 must
be tied to NTRL;
VB can be tied to
EGND for reversal
detection
