Section 3 User System Interface Circuits

The following user interface circuits are required for the emulator when the user system interface
board is in use.
Sub-MCU
PM0-PM4
Note: The power-supply circuit shown above is turned on/off by the setting of the SW1 jumper
pin on HS1664ECH61H. Ensure that the jumper pin is inserted to [USER-ON] on
HS1664ECH61H when connecting the emulator (with HS1664ECH61H attached) to the
user system or supplying power to DrVCC. Otherwise the emulator product, user system
interface board, and user system will be damaged.
