Section 5 Differences between the MCU (H8/38537F) and the Emulator
[Flash memory write after
download] group box
Enables or disables programming of the flash memory after
downloading the program.
Disable: Disables programming of the flash memory after
downloading the program.
Enable: Enables programming of the flash memory after
downloading the program.
Notes: 1. Includes interrupts in a break.
2. When Step Over is performed after selecting [No Programming of the flash memory]
for [Step Over option], the instruction that follows a JSR, BSR, or TRAPA instruction
will also be executed. If there are consecutive JSR, BSR, or TRAPA instructions,
execution proceeds until it reaches an instruction that is not JSR, BSR, or TRAPA.
(When there are consecutive function calls in C language, the program steps all of
these functions).
17. Initializing the Internal I/O Register with the Reset_CPU Function
Be sure to initialize the internal I/O registers shown below by the user program since they are
not initialized by selecting [Debug] – [Reset CPU] or using the RESET command.

18. Available MCUs for E8a Emulator
The H8/38534F is also available for the emulator. When the emulator is activated, set the
MCU to be selected as shown in table 5.4. Note that, however, an error will not be displayed
even if a program which is larger than the internal ROM capacity is downloaded.

19. Restriction on Software Write Enable (SWE) Bit
If the SWE bit is set to 1 during execution of the user program, a communication timeout error
will occur. Do not set this bit to 1.
