GPIO De-bounce Enable Register
The GPIO De-bounce Enable Register enables a de-bounce circuit to be applied to any GPIO line
designated as an input to filter relays, switches, and contacts. The circuit waits for 15ms of
glitch-free input signal before registering a change-of-state in the Data Register.
