CHAPTER2 Dependence Functions
Notes:
Hardware
The hardware break requires the following cautions:
• Do not set any hardware break in a 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 a breakpoint is set during
instruction execution, the program may malfunction.
Hardware/count
The hardware/count break requires the following caution:
• The hardware/count break can be used only when the FR60Lite or FR80S is used. For details,
refer to "2.3.4 Break".
• The pass count increases just by fetching an instruction of a break address.
