of the [Configuration] dialog box, a BREAKPOINT is set to a physical address. A
BREAKPOINT is set after disabling the SH7729 or SH7709A MMU upon program execution.
After setting, the MMU is returned to the original state. When a break occurs at the
corresponding virtual address, the cause of termination displayed in the status bar and the
[System Status] window is ILLEGAL INSTRUCTION, not BREAKPOINT.

is set after enabling the SH7729 or SH7709A MMU upon program execution. After setting,
the MMU is returned to the original state. When an ASID value is specified, the breakpoint is
set to the virtual address corresponding to the ASID value. The emulator sets the breakpoint
after rewriting the ASID value to the specified value, and returns the ASID value to its original
value after setting. When no ASID value is specified, the breakpoint is set to a virtual address
corresponding to the ASID value at command input.

breakpoint address remains unchanged. When a breakpoint is satisfied with the modified
address in the VP_MAP table, the cause of termination displayed in the status bar and the

A breakpoint is equal to a branch instruction. In some DSP repeat loops, branch instructions
cannot be set. For these cases, do not set breakpoints. Refer to the hardware manual for

user program execution cannot be terminated before the slot instruction execution; execution
stops before the branch destination instruction.
