Section 5 Differences between the MCU (H8/38704F) and the Emulator
[Short break] group box
Enables or disables memory access during user program
execution.
Disable: Disables memory access during user program
execution.
Enable: Enables memory access during user program
execution.
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.
