PRACTICE PROBLEM SOLUTIONS

1. both are similar. The timer and counter memories both use double words for the accumulator and presets, and they use bits to track the status of the functions. These bits are somewhat different, but parallel in function.

2. Inputs cannot be changed by the program, and some of the status bits/words cannot be changed by the user.

3.

4.

5.

6. three long words (3 * 32 bits) are used for a timer or a counter.

7.
