Voltage Sag Duration (VSAGduration, V2SAGduration) defines the number of instantaneous measurements utilized

to determine a sag event. Setting these register to zero will disable this feature. The value is represented in un-

signed notation. See Section 5.6 Sag and Fault Detect Feature on page 20

to determine a sag event. Setting these register to zero will disable this feature. The value is represented in un-

signed notation. See Section 5.6 Sag and Fault Detect Feature on page 20.

Default = 0x000000

Voltage Sag Level (VSAGlevel), V2SAGlevel) defines the voltage level that the magnitude of input samples, aver-

aged over the sag duration, must fall below in order to register a sag condition. These value are represented in

unsigned notation and in the range of 0 ≤ VSAGlevel < 1.0 (0 ≤ V2SAGlevel < 1.0), with the binary point to the left

of the MSB. See Section 5.6 Sag and Fault Detect Feature on page 20.
