Using breakpoints

►This hands-on lab shows you how to use breakpoints.

• Add breakpoints

• Add hardware breakpoints

• Set conditional breakpoints

• Skip breakpoints

• Disable/enable breakpoints

• Remove breakpoints

►The lab uses the DEMOQE128 board with the MC9S08QE128 daughter card.

►The application uses buttons connected to PTA2, PTA3, PTD2, PTD3

to turn on LEDs and sound tones.
