function of number of sample periods. The default corresponds to a pulsewidth of
512 samples/[(MCLK/K)/1024] = 128 msec with MCLK = 4.096 MHz and K = 1. The value is represented in un-
signed notation.
Address: 22
Default = 0x000000 = Hardware-generated pulse width (up to 125 µs)

Default = 0x000200 = 512 sample periods
PW sets the pulsewidth of E1 and E2 pulses in Alternate Pulse and Mechanical Counter format. The width is a
The PulseWidth register sets the pulse width of E3 pulses in units of 1/OWR.
E3 pulse width =
The range of this register is from 1 to 8388607.
Voltage Sag Duration (VSAG
termine a voltage level sag event (VSAG
value is represented in unsigned notation.
Default = 0x000000
Voltage Sag Level (VSAG
sag duration, must fall below in order to register a sag condition. This value is represented in unsigned notation
and in the range of 0 ≤ VSAG
