6.6.32 Voltage 1 Swell Duration (V1SwellDUR ) – Page 18, Address 46

Default = 0x00 0000

Voltage swell duration, V1SwellDUR, determines the count of OWR samples utilized to determine a swell

event.

These are integers in the range of 0 to 8,388,607 samples. A value of zero disables the feature.

6.6.33 Voltage 1 Swell Level (V1SwellLEVEL ) – Page 18, Address 47

Default = 0x7F FFFF

Voltage swell level, V1SwellLEVEL, establishes an input level above which a swell event is triggered.

This is a two's complement value in the range of -1.0

value1.0, with the binary point to the right of the MSB.

Negative values are not used.

6.6.34 Voltage 2 Swell Duration (V2SwellDUR ) – Page 18, Address 50

Default = 0x00 0000

Voltage swell duration, V2SwellDUR, determines the count of OWR samples utilized to determine a swell

event.

These are integers in the range of 0 to 8,388,607 samples. A value of zero disables the feature.

6.6.35 Voltage 2 Swell Level (V2SwellLEVEL ) – Page 18, Address 51

Default = 0x7F FFFF

Voltage swell level, V2SwellLEVEL, establishes an input level above which a swell event is triggered.

This is a two's complement value in the range of -1.0

 value  1.0, with the binary point to the right of the MSB.

Negative values are not used.
