able to
• Explain the difference between interrupts and
resets
• Describe the handling procedures for interrupts
and resets
• Raise one of the HCS12 maskable interrupts
to the highest priority
• Enable and disable maskable interrupts
• Use one of the low-power modes to reduce the
power consumption
• Use COP watchdog timer reset to detect
software failure
• Set up the interrupt vector jump table for
demo boards that have the D-Bug12 monitor
• Use RTI to generate periodic interrupts
• Write interrupt-driven application programs
• Distinguish the HCS12 operation modes
