Section 5 Differences between the MCUs and the Emulator
Table 5.2 Program Area for the E8a Emulator
MCU Name
H8/38076RF
H8/38086RF
H8/38776F
Program Area
Emulator ROM: H’C000 to H’CFFF
Internal RAM: H’F380 to H’F77F
Vector, etc.: H’0002 to H’00097, H’CFF8 to H’CFF9
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.
16. Forced Break Function
When the NMI# signal is used for a forced break in the emulator, the vector address of NMI#
is rewritten by the emulator program. An error will occur if a file in the host computer and the
flash memory contents are verified. Do not use the flash memory contents as the ROM data
for the mask ROM after it has been saved.
17. Setting the Usage of the NMI# Signal
In the [Configuration] dialog box, when the NMI# signal is changed as it is used in the user
program, the vector address of NMI# is not recovered. Reload the user program.
18. Address Break Release Function
In the [Configuration] dialog box, when the address break is changed as it is used in the user
program, Break Condition 2 is disabled in this emulator.
19. Hardware Break Functions
• In the H8/38076RF, H8/38086RF, H8/38776F E8a emulator, conditions of Break
Condition 1,2 can be set. Table 5.3 lists the items that can be specified.
Note: When the address break is used in the user program, Break Condition 2 is disabled.
