The current interrupts are: • INT Pin Interrupt (external interrupt) • TMR0 Over?ow Interrupt • PORTB Change Interrupt (pins RB7:RB4) • Comparator Change Interrupt • Parallel Slave Port Interrupt • USART Interrupts • Receive Interrupt • Transmit Interrupt • A/D Conversion Complete Interrupt • LCD Interrupt
the interrupt service routine while a wide pulse width must be greater then the maximum time through the interrupt service routine Example 1 shows a single interrupt source on PORTB (RB7) which executes the interrupt service routine on a rising edge The interrupt source has a small pulse width In this case since the interrupt pulse width is
The Nios II processor only has one interrupt handler so a register (ipending) must be polled to determine the source of the generated interrupt request Once the device is found the processor can select the appropriate Interrupt Service Routine (ISR) to be called The time needed to access this

SUMMARY The PORTB interrupt on change feature is both a very convenient method for direct interfacing to an external keypad, with no additional components, but is also versatile in its uses the ability to add up to four additional external interrupts. Of course hybrid solu- tions are also possible.
Example 2 shows a single interrupt source on PORTB (RB7), which executes the interrupt service routine on a rising edge . The interr upt source has a wide pulse width. In this case since the interrupt pulse width is large, the pulse is still high before PORTB is read to end the mismatch condition.
When this inter- rupt is used in conjunction with the software programmable weak internal pull-ups, a direct interface to a keypad is possible. This is shown in application note AN552, Implementing Wake-up on Key Stroke. Another way to use the “interrupt on change” feature would be as additional external interrupt sources.
