3. Bit 1 of PORT C Vx 330 Ohm PIC18F4321 LM33 Output. If Vx> Vy Vy LED ?RB0 >11 RBI / INT1 PORT B e above Figure, the PICI8F4321 is required to turn on an LED connected to bit 1 of PORT omparator voltage Vx > Vy; otherwise, the LED will be turned off. Use Interrupt I/O by conna oanparator output to INTI. Note that RB1 is also multiplexed with INTI. Write main progratin and interrupt service routine at 0x150 in PIC18F assembly language. The main program gure the LO ports, enable interrupt INT 1, initialize STKPTR to 0x30, turn the LED OFF, a (a) In th the comparator the comparator output to I ED OFF, and then wait for nterupt. The interrupt service routine will turn the LED ON and return to the main program . The e appropriate locati OVER PLEASE th Rie ocation so that the LED is turmed ON continuously until the next interrupt. (12 points) at 3. Bit 1 of PORT C Vx 330 Ohm PIC18F4321 LM33 Output.
