SENSE
resistor in use on the evaluation board. This value is used in calculations done by the
GUI. In Demo mode, select the
1 Ohm - Demo
button. In Sys mode, select the
0.005 Ohm - System
button. If another resistor is used, check the
Custom
option
button and fill the corresponding value in the spin box underneath the option.

Panel and Integration Control Panel
The Panel and Integration Control section, shown in
, contains GUI controls
which set and clear the INT_EN bit. When using these controls, check the “READ/INT
OVR” box in the Main Configuration section to allow the INT_EN bit to override the
READ/INT pin state.
