Important: To prevent indeterminate
system behavior, reserved areas of memory must not be accessed by software or
hardware. Any area of the memory map that is not explicitly defined as a register
space or accessible memory is considered reserved.

| 28:0 | gpio_debounce | Controls whether an external signal that is the source of an interrupt needs to be debounced to remove any spurious glitches. A signal must be valid for two periods of an external clock (gpio_db_clk) before it is internally processed. Note that only bits[26:0] are implemented for gpio2.
