Appendix D Notes on High-performance Embedded Workshop
15. Memory Access during User Program Execution
When a memory is accessed from the memory window, etc. during user program execution,
the user program is resumed after it has stopped in the emulator to access the memory.
Therefore, realtime emulation cannot be performed.
The stopping time of the user program is as follows:
Environment:
Host computer: 3 GHz (Pentium
SH7265R: System clock frequency 66.6 MHz
JTAG clock: 2.5 MHz
When a one-byte memory is read from the command-line window, the stopping time will be
about 20 ms.
16. BREAKPOINT Setting for SLEEP Instruction
When a break is set for the SLEEP instruction, use the Break Condition not the
BREAKPOINT.
17. Note on Session Save in the [Configuration] Dialog Box
The following settings are not saved as a session:
⎯ JTAG clock in the [General] page
⎯ Loading flash memory in the [Loading flash memory] page
18. Scrolling Window During User Program Execution
Do not scroll the [Memory] and [Disassembly] windows by dragging the scroll box during user
program execution. This generates many memory reads causing the user program to stop
execution until the memory reads have been completed.
19. Memory Test Function
This product does not support the memory test function, which is used by selecting [Test...]
from the [Memory] menu.
20. Memory Access during Flash Memory Programming
During flash memory programming (e.g., user program execution), operation for memory
accessing such as opening the [Memory] window is not allowed. Values displayed here are
dummy. Access the memory again after flash memory programming has been completed
.
