Erase Flash and Connect [*2]

Debugging
only [*1]
Description
When starting the debugger, the E8a emulator erases the Flash memory data for the MCUs
and simultaneously writes the E8a emulator program.
When launching the debugger, the E8a emulator retains the Flash memory data for the
MCUs. Note that the area for the E8a emulator program and the vector area used by the E8a
emulator will change.
Program Flash [*2]
Simple
programmer
The E8a emulator starts as a simple programmer. When downloaded, the E8a writes only
the user program (E8a emulator program is not written). Therefore, the program cannot be
debugged in this mode.
When [Execute the user program after ending the debugger.] is selected, with the E8a
emulator connected to the user system, the user program is executed at the same time the
debugger is terminated. This check box setting is available only when the [Program Flash]
mode is selected.
Debugging of CPU rewrite
mode
Debugging
only [*1]
Select this setting when debugging the program which rewrites the CPU. In this mode, the
following debug operation which rewrites the Flash memory cannot be executed.
- Setting the PC break points
- Changing the memory contents in the Flash memory area
In this mode, when starting the debugger, the E8a emulator erases the Flash memory data
for the MCUs and simultaneously writes the E8a emulator program.
Notes
[*1] These modes are available only for debugging. Programs written in these modes cannot be executed from the CPU.
If you want to execute a program from the CPU, use Program Flash mode.
[*2] When starting up in these modes, lock bits in all the blocks of the flash memory will be unlocked. Note that the lock
bits of the downloaded blocks will be unlocked after downloading the user program.
