Detailed Description

Interrupt support.

Macro Definition Documentation

QORIQ_PIC_PRIORITY_IS_VALID

#define QORIQ_PIC_PRIORITY_IS_VALID

(

p

)

Value:

(((uint32_t) (p)) <= QORIQ_PIC_PRIORITY_DISABLED)

Function Documentation

qoriq_pic_set_sense_and_polarity()

rtems_status_code qoriq_pic_set_sense_and_polarity	(	rtems_vector_number	vector,
		qoriq_eirq_sense_and_polarity	new_sense_and_polarity,
		qoriq_eirq_sense_and_polarity *	old_sense_and_polarity )

Change polarity and sense settings of external interrupts.

NOTE: There are only very rare edge cases where you need this function.

vector must be the vector number of an external interrupt.

Use new_sense_and_polarity to select the new setting. If old_sense_and_polarity is not NULL, the old value is returned.

Returns

RTEMS_SUCCSSSFUL on sucess or other values for invalid settings.
