■ Settings of the C-pin switch
Use the C-pin switch on the adapter board to switch the C-pin setting.
Figure 14 shows the peripheral circuit configuration of the C-pin switch. Table 7 lists the settings of
the switch.

■ Settings of the user data bus switch
If the probing target pins (P00 to P07, P10 to P17) have a special specification, such as for a high-
voltage port, set the user data bus probing circuit to "Disconnect."
When the external bus of the evaluation MCU is not used, "Disconnect" is the recommended setting
for the user data bus probing circuit.
Using the user data bus switch on the adapter board, set the user data bus probing circuit to "Connect"
or "Disconnect."
Figure 15 shows the peripheral circuit configuration of the user data bus switch. Table 8 lists the set-
tings of the switch.

Note : This circuit has a function equivalent to that of a high-resistance pull-up resistor.
When all buses of the evaluation MCU and user system are in the Hi-Z state, approximately 3.0V ap-
pears on the bus.
