Test CapSense Buttons with FSS and TOGGLE Feature Enabled
Touch more than one CapSense button; only one LED is turned on. When the same button is
released, the LED remains in ON state. Successive activation of button sensor makes the respective
output toggle between the ON and OFF states. At the same time, CapSense controller stops activa-
tion of more than one button together.
