WebThe BASEPRI register prevents interrupts with lower priority interrupts, but allows higher priority interrupts. For example if the software sets the BASEPRI to 3, then requests with level 0, 1, and 2 can interrupt, while requests at levels 3 and higher will be postponed. The software can also specify the priority level of each interrupt request. WebHardware Interrupt Example: Reading a keypad is made far easier using interrupts (especially on PIC devices) as PORTB has an interrupt-on-change feature for PortB pins.Attaching each pin to a push-to-make buttonand enabling the internal pullups on these pins gives you an easy way to read button presses.
