Note: The power-supply circuit shown above is turned on/off by the setting of the SW1 jumper
pin on HS1658RECN61H. Ensure that the jumper pin is inserted to [ON] on
HS1658RECN61H when connecting the emulator (with HS1658RECN61H attached) to
the user system or supplying power to DrVCC. Otherwise the emulator product, user
system interface board, and user system will be damaged.
