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.
REJ10J1007-0400 Rev.4.00 July 29, 2009
Note on Differences between the Actual MCU and Emulator:
Note on RESET# Input:
Note on RDY# Input:
Note on HOLD# Input:
Note on NMI# Input:
Operations of the emulator system differ from those of actual MCUs as listed below.
A low input to pin RESET# from the user system is accepted during the user program execution (only while the
RUN status LED on the emulator's upper panel is lit).
Be sure to input "L" to pin RDY# of the user system during the user program execution (when the RUN status
LED on the emulator’s upper panel is lit). Inputting "L" to pin RDY# during the user program is being stopped
may cause a malfunction of the emulator.
Be sure to input "L" to pin HOLD# of the user system during the user program execution (when the RUN status
LED on the emulator’s upper panel is lit). Inputting "L" to pin HOLD# during the user program is being
stopped may cause a malfunction of the emulator.
A low input to pin NMI# from the user system is accepted during the user program execution (only while the
RUN status LED on the emulator's upper panel is lit).
(1) Reset condition
(2) Initial values of internal resource data of an MCU at power-on
(3) Interrupt stack pointer (ISP) after a reset is released
(4) Capacities of the internal memories (ROM and RAM)
(5) Oscillator circuit
(6) A/D conversion
(7) Ports P0 to P5, P10
(8) Address and status of BHE#
(9) Status of a data bus
(10) Operation after releasing the reset
Set the time for starting up (0.2 VCC to 0.8 VCC) 1 μs or less.
The evaluation MCU of this product has RAM of 31KB (00400h--07FFFh) and flash ROM of 4KB
(0F000h--0FFFFh) and 512KB (80000h--FFFFFh).
In the oscillator circuit where an oscillator is connected between pins XIN and XOUT, oscillation does not
occur because a package 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 an oscillator circuit on the user system, refer to
"2.9.1 (2) Using an Oscillator Circuit on the User System" (page 47).
The characteristics of the A/D converter differ from those of actual MCU because there are a converter
board and other devices between the evaluation MCU and the user system.
This product emulates some I/O ports (P0 to P5, 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.
After releasing the reset, for about max. 380 cycles, a program to control the emulator will be executed.
Note that this will be included in the user program execution time and tracing result.
