3) Notes on debugger
Step execution of RETI instruction
If stepped execution is used in an environment where interrupts occur frequently, the interrupt processing
routines corresponding to those interrupts are executed repeatedly, and the programs for the main routine
and low-level interrupt routines are not able to execute as a result. (For example, if a reload timer is enabled,
execution will always break at the beginning of the reload timer interrupt routine when the RETI instruction
is step-executed.) Disable the corresponding interrupts when the interrupt processing routines no longer
need to be debugged.
Break function
If the target address of a hardware break (including event breaks) is set to the address of the current system
stack pointer or to an area that contains the stack pointer, execution will break after each instruction regardless
of whether the user program actually contains data access instructions.
To prevent this, do not set (word) access to the area containing the address of the system stack pointer as
the target of a hardware break (including an event break).
Operand break
Malfunctions may occur if the stack pointer is within an area which is set as the DSU operand break. Do not
set the access to the areas containing the address of system stack pointer as a target of data event break.
