int HAL_DisableIrq

(

uint8_t

irqNumber

)

Parameters:

[in]

irqNumber

- IRQ number

(

uint8_t

irqNumber

)

Enables the irqNumber interrupt.

Parameters:

[in]

irqNumber

- IRQ number

int HAL_RegisterIrq	(	uint8_t	irqNumber,
		HAL_irqMode_t	irqMode,
		void(*)(void)	f
	)

Parameters:

[in]	irqNumber	- IRQ number. Must be chosen from: IRQ_6 IRQ_7
[in]	irqMode	- Controls the sort of interrupt. Must be chosen from: IRQ_LOW_LEVEL // The low level generates an interrupt request. IRQ_ANY_EDGE // Any edge generates an interrupt request. IRQ_FALLING_EDGE // Falling edge generates an interrupt request. IRQ_RISING_EDGE // Rising edge generates an interrupt request.
[in]	f	- user's interrupt handler

Returns:

-1 - if irqNumber is out of range or such interrupt has been already registered.
0 - otherwise.

int HAL_UnregisterIrq

(

uint8_t

irqNumber

)
