void NVIC_SET_PENDING

(

uint32_t

IRQ

)

Set a pending interrupt for the specified interrupt in the ARM NVIC.

Parameters

IRQ	IRQ of relevant interrupt as specified in Table 3-7. on Page 52 of the KL25 Sub-Family Reference Manual.

Returns

Nil.

Set a pending interrupt for the specified interrupt in the Nested Vector Interrupt Controller (NVIC).

void NVIC_Set_Priority	(	uint32_t	IRQ,
		uint8_t	priority
	)

Set the priority of the specified interrupt in the ARM NVIC.

Parameters

IRQ	IRQ of relevant interrupt as specified in Table 3-7. on Page 52 of the KL25 Sub-Family Reference Manual.
priority	Priority of the interrupt. Value between 0 and 3.

Returns

Nil.

Set the priority of the specified interrupt in the Nested Vector Interrupt Controller (NVIC). The priority is a two-bit value with 0 being the highest priority.

Either a priority of 0 to 3 or 128
