Figure 10. Graphical interface at start-up (“settings” tab activated by default)
Clicking on
SWITCH
tab, a new window appears (see
). In the left side of the
window, the parameters of the IO connected to on-board switches (SW1 to SW4) can be
set. The parameters are:
• Latch:
enable / disable the corresponding latch of the input.
• Pull Up/Down Enable:
enable / disable the internal pull-up or pull-down resistor.
• Pull UP/Down Selection:
select the internal pull-up or pull-down resistor.
• Interrupt Mask:
enable / disable the interrupt mask for the input;
• Polarity Inversion:
enable / disable the polarity inversion function for the input;
The
Write
button sets the internal registers of the DUT with the selected value in the GUI.
The switches on-board switches (SW1 to SW8) does not have pull-up resistors, the user
should select and activate the internal pull-up resistors from the GUI. In the right side
