Enumeration Type Documentation

enum eint_intr_t

The type of the interrupt for the port pin.

Enumerator
eint_rising_edge	Interrupt on rising edge.
eint_falling_edge	Interrupt on falling edge.

Function Documentation

void eint3_enable_port0	(	uint8_t	pin_num,
		eint_intr_t	type,
		void_func_t	func
	)

Enables the callback when the interrupt occurs. The entry added last is checked first if multiple interrupts occur at the same time. Each call will allocate 16 bytes for the interrupt service entry.

Note

EINT3 shares interrupt with Port0 and Port2

Parameters

[in]	pin_num	The pin number from 0-31.
[in]	type	The type of interrupt.
[in]	func	The callback function.

void eint3_enable_port2	(	uint8_t	pin_num,
		eint_intr_t	type,
		void_func_t	func
	)

Enables the callback when the interrupt occurs. The entry added last is checked first if multiple interrupts occur at the same time. Each call will allocate 16 bytes for the interrupt service entry.

Note

EINT3 shares interrupt with Port0 and Port2

Parameters

[in]	pin_num	The pin number from 0-31.
[in]	type	The type of interrupt.
[in]	func	The callback function.
