6. When a BREAKPOINT is set to the slot instruction of a delayed branch instruction, the PC

value becomes an illegal value. Accordingly, do not set a BREAKPOINT to the slot

instruction of a delayed branch instruction.

7. When a BREAKPOINT is set to the cacheable area, the cache block containing the

BREAKPOINT address is filled immediately before and after user program execution.

8. If an address of a BREAKPOINT cannot be correctly set in the ROM or flash memory area, a

mark z will be displayed in the [BP] area of the address on the [Editor] or [Disassembly]

window by refreshing the [Memory] window, etc. after Go execution. However, no break will

occur at this address. When the program halts with the break condition, the mark z disappears.

2.2.6 Notes on Setting the [Break Condition] Dialog Box and BREAKCONDITION_SET

Command

1. When [Go to cursor], [Step In], [Step Over], or [Step Out] is selected, the settings of Break

Condition 2 are disabled.

2. Break Condition 2 is disabled when an instruction to which a BREAKPOINT has been set is

executed. Accordingly, do not set a BREAKPOINT to an instruction which satisfies Break

Condition 2.

3. When a Break Condition is satisfied, emulation may stop after two or more instructions have

been executed.

4. If a PC break address condition is set to the slot instruction after a delayed branch instruction,

user program execution cannot be terminated before the slot instruction execution; execution

stops before the branch destination instruction.

5. Note that a break occurs with a break satisfaction condition by an instruction that has been

cancelled due to the generation of an exception.

6. Use the sequential break or count break with the L-bus condition. If such break is used with

the I-bus condition, it will not operate correctly.

7. A break will not occur with the execution counts specified on the execution of the multi-step

instruction.

2.2.7 Notes on Setting the UBC_MODE Command

In the [Configuration] window, if [User] is set while the [UBC mode] list box has been set, the

STEP-type commands that use Break Condition 2 for implementation cannot be used.
