Public Types¶

Type	Name
enum	SYN_EXTI_Edge

Public Functions¶

Type	Name
void	syn_port_exti_clear_pending (SYN_GPIO_Pin pin) Clear pending interrupt flag for a pin.
SYN_Status	syn_port_exti_configure (SYN_GPIO_Pin pin, SYN_EXTI_Edge edge) Configure a pin for interrupt generation.
void	syn_port_exti_disable (SYN_GPIO_Pin pin) Disable interrupt on a pin (without deconfiguring).
void	syn_port_exti_enable (SYN_GPIO_Pin pin) Enable interrupt on a configured pin.

Detailed Description¶

Provides pin-change interrupt registration. The platform layer manages the hardware (NVIC, EXTI lines, etc.) and calls back into the syn_exti dispatcher.

enum SYN_EXTI_Edge¶

enum SYN_EXTI_Edge {
    SYN_EXTI_RISING = 0,
    SYN_EXTI_FALLING = 1,
    SYN_EXTI_BOTH = 2
};

Interrupt trigger edge.
