the [Configuration] dialog box, a BREAKPOINT is set to a virtual address. A BREAKPOINT
is set after enabling the SH7750R MMU during 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.

If a program is executed again without clearing the BREAKPOINT set at the address in which
the TLB error occurs, a TLB error will occur again. Accordingly, clear the BREAKPOINT
before execution.
BREAKPOINT is set. Accordingly, even if the VP_MAP table is modified after
BREAKPOINT setting, the BREAKPOINT address remains unchanged. When a
BREAKPOINT is satisfied with the modified address in the VP_MAP table, the cause of
