I need help with this assignment:

I am using CodeWarrior

Use the polling method to write an assembly program to count the number of times the free-running timer overflow (TOF is raised). Display the counts as a binary number using LEDs on the microcontroller training board.

Suggestions: You can refer to the example program in the Unit 4 Lecture 7 and subroutine InitLEDs from an earlier lab assignment. But, you must understand every line of code.

I have this code so far:
