ADRESH REGISTER VALUE

6.

Adjust the POT and continue the program by selecting Debug > Run. The 
program will run through the loop and halt. 

7.

Hover over “ADRESH” again, the A/D result has not changed. Thus it seems the 
A/D conversion is not working. The A/D conversion initialization and setup occurs 
at the beginning of the program.

FIGURE 4-23:

PROGRAM HALTED

8.

Select Debugger > Reset to reset the program. The first instruction should be 
indicated by a green arrow.

9.

Select View > Watch to open a new Watch window. This window allows the user 
to watch the A/D register value change as the program executes. The Watch 
dialog opens with the Watch_1 tab selected, as shown in Figure 4-24.
