CHAPTER2 Dependence Functions
Notes:
Hardware
The hardware break requires the following cautions:
- Do not set any hardware break in instruction placed in a delay slot. When the hardware break
is set in the instruction, a branch does not occur even if the program is reexecuted after break.
- Be sure to set a breakpoint at the starting address of the instruction. A break may not occur if
an address other than the starting address is specified.
- When the program is executed from the address at which a hardware break is set, a break
occurs without executing the instruction if the immediately preceding program execution is
stopped by a factor other than the instruction break. To execute the instruction, reexecute the
program.
Software
The software break requires the following cautions:
- A breakpoint cannot be set in any area, such as ROM, where data cannot be written properly.
In this case, a verify error occurs when program execution is started (continuous execution or
stepwise execution is started).
- Be sure to set a breakpoint at the starting address of the instruction. If breakpoint is set during
instruction execution, the program may malfunction.
