Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

| 23:0 | gpio_inten | Allows each bit of Port A to be configured for interrupts. By default the generation of interrupts is disabled. Whenever a 1 is written to a bit of this register, it configures the corresponding bit on Port A to become an interrupt; otherwise, Port A operates as a normal GPIO signal. Interrupts are disabled on the corresponding bits of Port A if the corresponding data direction register is set to Output or if Port A mode is set to Hardware. 0 Configure Port A bit as normal GPIO signal (default) 1 Configure Port A bit as interrupt
