Schematic Diagram To turn on an LED, we will have to send '1' to the corresponding PORTD pin. This can be done by setting the corresponding bit in the LATD register using the BSF F,b instruction. Similarly, the LEDs can be switched off individually by clearing the corresponding bit of the LATD register using the BCF F,b instruction. Complete the activity in the following format: #include PSECT Start Org 0 Start: ; Configure RD6 as Digital Output ; Set RD6 to turn on the LED ; Wait here $ GOTO END Use the MPLAB simulator to single-step the program and examine the registers. Now use the Proteus Professional to simulate the hardware connections. Load the hex file into the microcontroller and see the simulation results.
