IMPORTANT
Notes on Downloading Firmware:
• Before using this product for the first time, it is necessary to download the dedicated firmware
(control software built into the PC7501). Please note that, to do this, it is necessary to start up the
PC7501 in maintenance mode. For firmware download procedures, see "4.2 Downloading
Firmware" (page 50). Once the firmware has been downloaded, the product can be used by simply
turning on the power.
• Do not shut off the power while downloading the firmware. If this happens, the product will not
start up properly. If power is shut off unexpectedly, redownload the firmware.
• Except when a target status error occurs, if the self-check is not completed successfully, there may
be trouble with the product. In such case, contact your sales representative. However, perform the
self-check while not connecting the target system.
Note on Quitting the Emulator Debugger:
• To restart the emulator debugger after it ends, always shut power to the emulator module off once
and then on again.
Note on Differences between an Actual MCU and the Emulator:
• Operations of the emulator differs from those of mask MCUs as listed below.
(1) Reset conditions
(2) Initial values of internal resource data at power-on
(3) Interrupt stack pointer (ISP) after releasing reset
(4) Internal memories (ROM and RAM) capacities, etc.
This emulator system has an MCU with 24KB RAM (400h--63FFh). In single-chip mode or
memory expansion mode, internal flash memory is automatically allocated in F000h--FFFFh
and F80000h--FFFFFFh, and it can be accessed.
(5) Oscillator circuit
• Make note of the fact that in the oscillator circuit where a resonator is connected between
pins X
IN
and X
OUT
, oscillation does not occur because a converter board and other devices
are used between the evaluation MCU and the target system. It is same for a sub-clock
oscillator (X
CIN
and X
COUT
).
• For notes on when using the oscillator circuit on the target system, refer to "3.3 Using the
Oscillator Circuit on the Target System" (page 30).
(6) A-D conversion
As a converter board and other devices are used between the evaluation MCU and the target
system, some characteristics are slightly different from those of an actual MCU.
(7) Port P15
As one of I/O ports (P15) is connected to the target system through the analog switch circuit,
electric characteristics slightly differ from those of an actual MCU.
(8) When the SW4 is set to XOUT in stop mode, a clock is output from the XOUT pin.
