The Toggle feature is controlled by the hardware configuration on Toggle/FSS pin. For details, refer to
The state of GPx changes on every rising edge of CSx CapSense status
When Toggle is enabled, Delay Off is disabled
Delay off time is controlled by the hardware configuration on the delay pin. For details, see
To enable delay off with Delay ‘D’ (multiple of 20 ms), a resistor ‘R’ should be connected between the delay pin and ground where
R = (Dx4) + 40 s
Delay off value specifies the duration for which the GPOx is driven low after the corresponding CapSense input CSx is released.
See
When a button gets reset, delay off is not applied on the corresponding GPO
Delay off feature is applicable to only one GPO at any point of time. In
delay off time) because CS1 button is released. Therefore, the delay counter is reset. Now, GPO1 remains low for delay off time
after releasing CS1
Delay off feature is applicable to the GPO of the last button released
Delay off range: 0 ms to 2000 ms
