Processor : ADSP-BF707
Attached is the GPIO example code for ADSP-BF707. By default, PORT interrupts are level-sensitive, triggering when an enabled pin is detected as active high. To configure the interrupts for edge sensitivity (i.e., to trigger on a rising edge), use the PINT_EDGE_SET register. To invert the polarity so that interrupts are generated on active-low signals or falling edges, use the PINT_INV_SET register.
This code demonstrates all type of interrupt generation such as,
1) Level sensitive
- Active High Interrupt
2) Edge Sensitive
- Rising Edge Interrupt
- Falling Edge Interrupt
The example can be run directly on the ADSP-BF707 EZ-KIT.
