(1) Hardware break function
The hardware break function is used to observe the CPU bus cycles and set a break for a specific fetch or
access operation. For example, a break can be set by detecting a state where an address has been
executed or a variable has been accessed. For states that can be set, see "Event function".
Caution The address for which a break has been set is at a position ahead of the address where an
actual access has occurred, because the break set for the access (write, read) is detected at an
MEM stage or a WB stage on the CPU pipeline.
(2) Software break function
The software break function is used to set a break when a specific address has been executed (fetched).
(3) Timer overflow break function
This function is used to set a break when a time set by using the time measurement function has elapsed.
For example, if the execution time of a function must be 2 ms, a break can be set when at least 2 ms have
elapsed between starting and ending the function.
