value becomes an illegal value. Accordingly, do not set a BREAKPOINT to the slot
instruction of a delayed branch instruction.
the [Configuration] dialog box, a breakpoint is set to a physical address or a virtual address
according to the SH7727 MMU status during command input when the VPMAP_SET
command setting is disabled. The ASID value of the SH7727 PTEH register during command
input is used. When VPMAP_SET command setting is enabled, a breakpoint is set to a
physical address into which address translation is made according to the VP_MAP table.
However, for addresses out of the range of the VP_MAP table, the address to which a
breakpoint is set depends on the SH7727 MMU status during command input. Even when the
VP_MAP table is modified after breakpoint setting, the address translated when the breakpoint
is set valid.
of the [Configuration] dialog box, a BREAKPOINT is set to a physical address. A
BREAKPOINT is set after disabling the SH7727 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.
the [Configuration] dialog box, a BREAKPOINT is set to a virtual address. A BREAKPOINT
is set after enabling the SH7727 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
