Voltage Sag Duration (VSAG Duration ) and Current Fault Duration (ISAG Duration ) defines the number of instanta-
neous measurements utilized to determine a sag event. Setting these register to zero will disable this feature.
The value is represented in unsigned notation. See Section 5.6 Sag and Fault Detect Feature on page 19.

Voltage Sag Level (VSAG Level ) and Current Fault Level (ISAG Level ) defines the voltage level that the magnitude
of input samples, averaged over the sag duration, must fall below in order to register a sag/fault condition. These
value are represented in unsigned notation and in the range of 0 ? VSAG Level ? 1.0, with the binary point to the
right of the third MSB. See Section 5.6 Sag and Fault Detect Feature on page 19.
