Section 5 Differences between the MCUs and the Emulator
10. Sum Data Displayed in the Program Flash Mode
Sum data, which is displayed in the ‘Program Flash’ mode, is a value that data in the whole
ROM areas has been added by byte (including data in the dedicated ROM area for the
emulator).
11. Note on Executing the User Program
The set value is rewritten since the emulator uses flash memory and watchdog timer registers
during programming (Go, Step In, Step Out, or Step Over) of the flash memory.
12. The power consumed by the MCU can reach several milliamperes. This is because the user
power supply drives ICs to make the communication signal level match the user-system
power-supply voltage. The power consumed rises little during user program execution since
the emulator does not perform communication; it rises more during a break.
13. Program Area for the Emulator
Do not access a part of areas in the flash memory or the internal RAM since the emulator
program uses these areas. If the contents of the program area for the emulator are changed, the
emulator will not operate normally. In this case, restart the emulator with the Erase Flash and
Connect mode.
Table 5.2 Program Area for the Emulator
MCU Name
H8/3672F
H8/36014(G)F
H8/36024(G)F
Program Area
Flash memory: H’4000 to H’4FFF
Internal RAM: H’F780 to H’FB7F
Vector, etc.: H’0002 to H’0007, H’000E to H’000F, H’0018 to H’0019
Flash memory: H’7000 to H’7FFF
Internal RAM: H’F780 to H’FB7F
Vector, etc.: H’0002 to H’0007, H’000E to H’000F, H’0018 to H’0019
14. The emulator uses a two-word stack pointer for values stored on a user program break.
Therefore, the stack area must accept two-word addresses.
15. Do not use an MCU that has been used for debugging.
If the flash memory is rewritten many times, data may be lost due to retention problems after
the emulator has been left for a few days and the data will be erased. If an error message is
displayed, exchange the MCU for a new one.
