on_kp_overflow Event

Function:	Indicates that the keypad event FIFO has overflown and some key events may have been lost.
Declaration:	on_kp_overflow
See Also:	Handling Keypad Buffer Overflows

Details

Once the FIFO overflows, the keypad is disabled (kp.enabled = 0 — NO). You can re-enable the keypad by setting kp.enabled = 1 — YES (this will also clear the FIFO).

Another on_kp_overflow event is never generated until the previous one is processed.
