Select a user port power supply for the evaluation MCU.
I Switching of the user port power supply
CAUTION
Prohibition
On the emulator, use the jumper for switching the user port power supply to set the reference
voltage of the user data bus probing circuit.
The user data bus for which the reference voltage is set corresponds to user ports 0 and 1. Set
the user port reference voltage for each port power supply source.
For details on the user data bus probing circuit, see Section 3.6 "User Data Bus Switching."
