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
MD_CLK
PM0-PM4
Note:
The power-supply circuit shown above is turned on/off by the setting of the SW1 jumper
pin on HS1653ECN61H. Ensure that the jumper pin is inserted to [ON] on
HS1653ECN61H when connecting the emulator (with HS1653ECN61H attached) to the
user system or supplying power to DrVCC. Otherwise the emulator product, user system
interface board, and user system will be damaged.
