The code I have written so far only blinks constantly regardless of which switch is HIGH or LOW.. I can't seem to figure out how to make one switch faster than the others because it would either blink all switches at same rate or remain steady (doesn't blink). Could anyone help me out?????? Thank you!

Write a program that scans the switch settings and adjusts the blink rate of and LED according to those switch
settings.

Your task is to write a program that detect the switch setting and slow down the flashing of the LED as each switch is set from LOW to HIGH. Your program should look like this. Note: ICSA.asm and switches.asm contain pieces of what you need.

1. Scan the switches
a. If Switch 1 is HIGH then change the blink timer and make it flash slower
b. If Switch 2 is HIGH then change the blink timer and make it flash slower
c. If Switch 3 is HIGH then change the blink timer and make it flash slower
d. If Switch 4 is HIGH then change the blink timer and make it flash slower
e. If Switch 5 is HIGH then change the blink timer and make it flash slower
f. If Switch 6 is HIGH then change the blink timer and make it flash slower
g. If Switch 7 is HIGH then change the blink timer and make it flash slower
h. If Switch 8 is HIGH then change the blink timer and make it flash slower
2. Blink the LED
3. Goto Scan the switches
