Question: Write an Assembly program for the ATMega32 that does the following:

1. Display a running light sequence of 8 values on 8 LEDs connected to Port B

2. When the sequence ends, restart and continue forever.

The following restrictions apply...

1. The light sequence (8 values) must be stored in a table in CSEG

2. Only one of the 8 LEDs may be on at any time

3. The LEDs are connected in an active low manner - accommodate for this

4. Use Timer 1 to implement a visualisation delay as follows...
a. Timer 1 mode: Normal
b. Timer 1 clock source: Prescaled system clock (Use prescalar of 8 with assumption system clock is 16MHz)
c. Use polling of the Timer 1 Overflow Flag to implement a 3 second delay
d. The polling routine must be a callable subprogram
e. The subprogram is called as needed from the main loop

5. Explicitly Set or Clear bits in the appropriate I/O registers. Assume that all bit values are initially wrong.

6. Structure your program very clearly and logically into blocks of code.

7. Comment every code block - indicating the purpose of the code
