8 interrupt program design and circuit simulation LPC2138 microcontroller interrupt managed by the Vectored Interrupt Controller VIC operations, vectored interrupt controller has 32 interrupt request inputs (32 interrupt channels, but uses only 19 LPC2138 channel number 0 to 18) they can be set to FIQ, vectored IRQ and non-vectored IRQ, by programming the various peripherals vectored IRQ interrupt priority level can be adjusted dynamically allocated. Definition buzzer output port, the use of registers PINSEL0, PINSEL1 EINT3 wake up the chip set, clear EINT3 interrupt flag. Use while, if-else loop to set the timer, buzzer. The timer, RTC, serial feature off in power-down mode, use IO0SET, IO0CLR register controls the buzzer beeps.
