12.2.5 Hardware Event
•
The debugger does not support a command fetch (Fetch) or an interrupt as a hardware event.
•
If you specify word-length (2-byte length) data from an odd address as an event in the following
data accesses, the event is not detected. Also, even when any other bit of the address that
contains a specified bit is accessed during bit access, the event may become effective.
- Hardware Break Event
- Real-time Trace Event
- Time Measurement Event
•
In the PID setting, you can specify the access size (BYTE/WORD). However, if you specify an odd
address in the "Address:" field, you cannot specify the WORD size.
•
Examples to specify the event for data access with its value comparison.

12.2.6 Time Measurement Resource
You need to specify the operating frequency of mcu for debugger to calculate the time for Trace
window, Time measurement window, or other functions.
You can set it in MCU tab of INIT dialog box. If you use the mcu at 10MHz div 8, please enter 10 and
8 to edit boxes.
12.2.7 CPU rewrite
You can not debug the program using CPU rewrite.
12.2.8 MR STK script command
•
The MR STK BASE command automatically sets the area where the stack consumption can be
measured. The area set by this command is range of 256KB including the start address of the
system stack. If you want to set other area, please use not the MR STK BASE script command
but the CoVerage BASE script command.
