E702289_SH7290 Datasheet, PDF (234/252 Pages) Renesas Technology Corp – SH7290 E10A Emulator

breakpoint is set depends on the SH7290 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.
10. When the [Physical] option is selected in the [Memory area] group box in the [General] page
of the [Configuration] dialog box, a BREAKPOINT is set to a physical address. A
BREAKPOINT is set after disabling the SH7290 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.
11. When the [Virtual] option is selected in the [Memory area] group box in the [General] page of
the [Configuration] dialog box, a BREAKPOINT is set to a virtual address. A BREAKPOINT
is set after enabling the SH7290 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.
12. An address (physical address) to which a breakpoint is set is determined when the 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 termination displayed in the status bar and the
[System Status] window is ILLEGAL INSTRUCTION, not BREAKPOINT.
6.5.6 Notes on Setting the [Break Condition] Dialog Box
1. Break Condition 2 is disabled during step execution.
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. Break Condition 1,2 is used as the measurement range in the performance measurement
function when (P) is added and displayed as Enable(P) on the [Condition] page. This applies
when the Break Condition is displayed with the BREAKCONDITION_DISPLAY command
in the command-line function. In this case, a break does not occur when Break Condition 1,2
is satisfied.
