The GPIO driver generates call back events that are notified via the function ARM_GPIO_SignalEvent.
This section provides the event values for the ARM_GPIO_SignalEvent callback function.
The following call back notification events are generated:
#define ARM_GPIO_EVENT_RISING_EDGE (1UL << 0) |
Rising-edge detected.
#define ARM_GPIO_EVENT_FALLING_EDGE (1UL << 1) |
Falling-edge detected.
#define ARM_GPIO_EVENT_EITHER_EDGE (1UL << 2) |
Either edge detected (only when hardware cannot distinguish between rising and falling edge)
