- 33. 33 EEM General Features Breakpoints: 2 to 8 available in hardware Complex breakpoints available Break if read/write at specified address Protection of read/write areas within Memory All timers & counters can be stopped (LCD is NOT stopped) USART can be stopped: clock source-dependent Single step/step into & over/run in real-time Full support of all low power modes Support for DCO dependencies such as temperature and voltage
- 34. 34 Example: The CPU should stop if a value not equal to 0xA0A0 is written into a variable. The variable wSetBreakpointOn is statically located in RAM. Break on Write to Address
- 35. 35 Example: The CPU should stop if a write access into Flash memory occurs (0xE000 to 0xFFDE in this case). Break on Write to Flash
- 36. 36 Example: CPU halts if an attempt to fetch an instruction out of the allowed memory range occurs (outside of main memory in this case). Break on Instruction Fetch out of Range
- 37. 37 Highly flexible trace buffer Trace on instructions Trace on triggers Trace cycles / CPU clocks Buffer wrap-around enable/disable Buffer can store up to 8 events Configurable Trace Buffer
- 38. 38 Trace on triggers set to variable read and/or write creates a real-time watch system Limitation: With more than one variable watch, a variable which is addressed infrequently may not be captured State Storage: Real-Time Watch
- 39. 39 Can create a linear program sequence before a trigger is accepted for a break or state storage event Useful if an event occurs only after a given sequence in the program has taken place Trigger Sequencer
