Section 3 Connectors, Switches, and LEDs
After program transfer, press the transfer switch
(START/STOP) and confirm that the START LED (red) is
turned off. If the user system power supply VIN (Vcc: 2.7 V
to 5.25 V, PVcc: 2.7 V to 5.25 V) is turned off while the
START LED is on, the user system will be damaged.
For details on activating the on-board programming tool, refer to the On-Board Programming
Tool User's Manual.
Activate the on-board programming tool, and select the boot mode or user program mode
displayed on the host computer. The hardware setting sequence is displayed. Then press the
transfer switch. The START LED (red) is turned on and a programming control is initiated.
After programming the flash memory in the selected mode, confirm the end message, press the
transfer switch again, and complete the programming control. At this time, the START LED is
turned off.
3.2.2
Power-Supply Switch (POWER)
The following two power-supply methods are available for this adapter board.
• Power is supplied from the user system power supply via the user system interface cable and
connector (VIN pin).
• As a countermeasure against insufficient current supply by the above method, power is
supplied through the power-supply connector (P3). In this case, the user must prepare a
separate power supply.
Vcc 5 V ± 5% is supplied to the power-supply connector (P3) of the adapter board. This switch
works as the power-supply switch (on and off) of the adapter board only when power is supplied
from the power-supply connector (P3) of the adapter board. (Refer to figure 3.3.) In this case,
power also needs to be supplied through the VIN pin of the user system interface cable.
When power is supplied to the adapter board only from the user system power supply, this power-
supply switch does not work. In this case, the power-supply switch on the user system is used as
the power-supply switch for the adapter board.
