Question

Write a complet assembly program (assember directives, initialization, main routine and subroutines) to implement the logic for a car interior lighting sysyem:

- If the sysytem is enabled (mode switch is in "Enable" position), and any of the four door switches are activated, then the light should turn on. The light should turn off if all doors are closed, or if the system is disabled( mode switch is in the OFF position).

- In addition, the light should turn off after 1 minute if somebody forgets to completely close the door. Assume a system clock of 128 kHZ. You may use any timer in any mode.

- You should also be able to manualy turn the light on (non-timed) by moving the mode switch to the ON position.

You may use any pin checking methoed (poling, scanning, interrupts, or a combination of the methods). Instead of re-writing,
