ALL=no
GPIO Interrupt Dual Edge Mode Register. Each bit in this register selects dual edge mode for the associated GPIO pin in this port.
ALL | Mask of all of the pins on the port. 0 (no): No Effect. 1 (en): Dual Edge mode is enabled. If edge-triggered interrupts are enabled on this GPIO pin, then both rising and falling edges will trigger interrupts regardless of the GPIO_INT_POL setting. |
