R0E436640CPE00 User's Manual

Notes on mode transition:

Mode transition is initiated by an interrupt. However, because the emulator generates an emulation-only
interrupt when one of the following operations is performed, it is possible that an unexpected mode transition
will occur while no interrupts have ever been generated in the user program itself.
- Forcible break (caused by entering the Esc key or pressing the Halt toolbar button)
- Break specified in an event detection system
- Single-stepping (Step In, Step Over, or Step Out)
- Program is run by Go from the SLEEP instruction address to which a software break has been set

Notes on the reserved areas:

In the actual MCU, the reserved areas are not guaranteed of program operation. When debugging a program that
resides partly in the reserved area for reasons of memory size, we recommend selecting the MCU that has the
largest ROM size available.
Since the compact emulator emulates multiple target MCUs using a single evaluation MCU, it occurs that the
compact emulator has I/O registers other than those of the target MCU. Therefore, be careful not to access the
unused addresses in the I/O register area. The values read or written to those addresses cannot be guaranteed.
Note also that the addresses H'F000 to H'F0FF comprise an area used by the compact emulator, so do not
access this area. The values read or written to those addresses cannot be guaranteed.

Notes on EEPROM:

To permit the H8/36xxN (with built-in EEPROM) to be evaluated, this product has a serial EEPROM mounted
directly in the conversion boards R0E436640CFG20 and R0E436640CFK20, one in each. When evaluating the
H8/36xxN, be sure to select the MCU file "H836xxN.mcu" in the emulator debugger. Note that although the
H8/36xxN permits the slave address code of its internal EEPROM to be rewritten to H'00–H'07, the slave
address of the serial EEPROM mounted on the conversion board is fixed to H'00 (default for the internal
EEPROM of the H8/36xxN). Note also that this EEPROM can be rewritten up to 100,000 times. When this
rewrite limit is exceeded, please purchase a new conversion board.
The serial EEPROM mounted on the conversion board has P57/SCL and P56/SDA connected to it, with 10 kΩ
pullup resistors included. Pay careful attention when you select pullup resistor values for the target system. The
pullup resistors of the target system affect the rise and fall times of signals depending on their selected values.
In the worst case, the serial EEPROM cannot be accessed correctly.

Note on DC Characteristics:

Because a protective serial resistance, analog switches and other devices are used between the ports, the DC
characteristics are different from those of an actual MCU. Make note on this when using this product.

Note on Final Evaluation:

Be sure to evaluate your system with an evaluation MCU. Before starting mask production, evaluate your
system and make final confirmation with a CS (Commercial Sample) version MCU.
