4.3 Differences between the Actual MCU and Emulator
Differences between the actual MCU and emulator are shown below. When debugging the MCU using this product, be careful
about the following precautions.
Note on Differences between the Actual MCU and Emulator:
Note on Emulating External Area:
Operations of the emulator system differ from those of actual MCUs as listed below.
To emulate the external area using emulation memory in this product, set 0 wait (8MHz) or less or 1 wait or
more.
(1) Reset condition
(2) Initial values of internal resource data of an MCU at power-on
(3) Internal memories (ROM and RAM) capacities etc.
(4) Oscillator circuit
(5) A/D converter function
(6) Characteristics of ports P0 to P5, and P10
(7) Address and status of BHE#
(8) Status of a data bus
(9) ALE signal
(10) Pins P57/CLKout
(11) DBC, single-step and BRK instruction interrupt vector table addresses
*1 Interruption for the emulator only
Table 4.8 Vector table addresses for the emulator
Set the time for rising (0.2 Vcc to 0.8 Vcc) and falling (0.8 Vcc to 0.2 Vcc) 1μs or less.
With this emulator system, regardless of ROM and RAM of the MCU you use, all the areas other than
the SFR area and a reserved area (addresses 27000h--27FFFh) can be read and written into.
Because a converter board, flexible cable and other devices are used between the evaluation MCU and
the user system, the A/D converter operates differently from that of the actual MCU.
This product emulates some I/O ports (P0 to P5, and P10). Therefore, the electrical characteristics of
these ports differ from those of an actual MCU.
When the internal RAM or ROM area of an MCU is accessed during user program execution, actual
MCUs retain a preceding address and status of BHE#, while this product does not.
In stop or wait mode, actual MCUs retain a preceding status of a data bus, while with this product a data
bus is floating.
When the internal RAM or SFR area of the MCU is accessed during user program execution, with the
actual MCU, ALE output is fixed to Low, while this product outputs ALE signal.
When pins P57/CLKout are used for CLKout function and Fc is selected by Clock output selection in
stop mode, CLKout output does not stop.
As the emulator uses the DBC, single-step and BRK instruction interrupt vector table addresses, when
reading these addresses, the downloaded data cannot be read (see Table 4.8).
In the oscillator circuit where an oscillator is connected between pins XIN and XOUT, oscillation does
not occur because a flexible cable or converter board is used between the evaluation MCU and the user
system. It is same for pins XCIN and XCOUT. For notes on when using the oscillator circuit on the user
system, refer to "2.9.3 (5) Using the Oscillator Circuit on the User System" (page 44).
