2.1 Handling Precautions

When using the M34282T5-OPT board, pay attention to the following:

(1) About an emulator system

To configure the emulator system with the M34282T5-OPT, the following products are required.

a. Emulator main unit (PC4000E)

This is an universal emulator main unit for the 720 Series.

b.Emulator card cage (PC4400)

This is an emulator card cage to contain the emulator main unit, control board, function

extension board and M34282T5-OPT board.

c. Control board (PCA4400A)

This is an emulator control board for the PC4400 system. The PCA4400A allows the user to

control program execution and reference/change contents of memory, as well as control break

functions etc. of the PC4400 system.

d.Function extension board (PCA4400R)

This is used by inserting into the PC4400, and allows the user to control real-time trace, program

execution time measurement, coverage analysis, etc. of the PC4400 system.

e. Power supply

As the PC4400 emulator system does not contain the power supply, the M34282T5-OPT should

be powered separately by an external power supply such as a switching power supply or a

stabilized power supply. For an external power supply, chose the one which suit to the

specifications below.

- For +5 V: 3.0 A or over

- For +12 V: 0.1 A or over

f. Emulator debugger (RTT72)

data files for 4282 Group.

For details, refer to the user's manual of RTT72.

Before installing (and removing) the MCU board, always be sure to power off the PC4000E

emulator main unit and unplug its power cord from the outlet.
