M30850T2-CPE User’s Manual
4.2 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.
REJ10J0865-0300 Rev.3.00 December 16, 2005
Notes on the User System (Power Supply, Order of Powering On):
Notes on Using This Product When the Voltage of VCC1 is Higher than That of VCC2:
These precautions only need to be observed when using an emulator, and does not apply for the actual MCU.
When the user system is connected, be sure to set the JP1 of the emulator to "EXT".
This emulator cannot supply the power to the user system. Therefore design your system so that the user system
is powered separately.
This emulator consumes max. 500 mA of electric current from the user system.
The voltage of the user system should be as follows.
(1) When JP1 of the M30850T2-EPBM is set as VCC1 = 2:
(2) When JP1 of the M30850T2-EPBM is set as VCC1 > 2:
Do not change the voltage of the user system after turning on the power.
If using this product when the voltage of VCC1 is higher than that of VCC2, set the JP1 to VCC1>2. For the
switch JP1, refer to "2.9 Changing Settings" (page 39).
When the JP1 is set to VCC1>VCC2, the voltage of VCC2 on the user system should be 3.3 V or more.
If using a CPU clock of more than 30MHz when the voltage of VCC1 is higher then that of VCC2, set the SFR
area of the intelligent I/O function to 2-wait (set the PM13 bit to “1”) when reading this area.
3.0 V ≤ VCC1 = VCC2 ≤ 5.5 V
4.8 V ≤ VCC1 ≤ 5.2 V
3.3 V ≤ VCC2 < VCC1
