Question

By considering Edsim51 simulator, write an 8051 assembly code for the following scenario:

1- At the beginning, number 0 is displayed on the Disp0 and Disp3, The rightmost and leftmost 7-segments, respectively.

2- for each time that switch #0 is closed and opened, one unit should be incremented to the number that is shown on Disp0. if it is 9, it doesn't change.

3- for each time that switch #1 is closed and opened, one unit should be decremented from the number that is shown on Disp0. if it is 0, it doesn't change.

4- for each time that switch #2 is closed and opened, two units should be incremented to the number that is shown on Disp3. if it is 8, it doesn't change.

5- for each time that switch #3 is closed and opened, two units should be decremented from the number that is shown on Disp3. if it is 0, it doesn't change.

 

The order of closing the switches is not determined, but when a switch is closed, the system waits until that switch becomes open again. meanwhile, the other switches are not working. 

Assume that the lookup table for 7segment exists on memory at address 0F00h.
