4.3.17 GPIO_DEBOUNCENABLE Register

The GPIO_DEBOUNCENABLE register is used to enable/disable the debouncing feature for each input
line. The GPIO_DEBOUNCENABLE register is shown in

4.3.18 GPIO_DEBOUNCINGTIME Register

The GPIO_DEBOUNCINGTIME register controls debouncing time (the value is global for all ports). The
debouncing cell is running with the debouncing clock (32 kHz), this register represents the number of
the clock cycle(s) (31μs long) to be used. The GPIO_DEBOUNCINGTIME register is shown in
