Question: The PIC18F4321 microcontroller is required to test a NAND gate. Figure shows the I/O hardware needed to test the NAND gate. The microcontroller is to be programmed to generate the various logic conditions for the NAND inputs, input the NAND output, and turn the LED ON connected to bit 3 of Port D if the NAND gate chip is found to be faulty. Otherwise, turn the LED ON connected to bit 4 of Port D. Write a PIC18F assembly language program at address 0x100 to accomplish this.
