You are designing a control system where two LEDs are connected to two separate pins. Write a short assembly snippet that first turns on the first LED, and then uses bit manipulation to turn off the second LED only if the first LED is already turned on.
💡 Hint: Consider how jumps can manipulate flow based on previous bit states.
In your program, you need to continuously toggle a status LED connected to pin P1.0 every millisecond. Write a brief code segment outlining how you will utilize the Carry flag alongside the SETB and CLR instructions to ensure accurate timing.
💡 Hint: Using the Timer helps ensure each toggle occurs precisely every millisecond.
