1. RENESAS ENESAS Section 1 Inside the E8 E8a Emulator User s Manual The E8 or E8a emulator hereafter referred to as E8 E8a in this document manual consists of two documents the E8 E8a User s Manual and the E8 E8a Additional Document for User s Manual this document Be sure to read BOTH documents before using the E8 E8a emulator 1 E8 E8a Emulator User s Manual The E8 E8a Emulator User s Manual describes the hardware specifications and how to use the emulator debugger E8 E8a emulator hardware specifications Connecting the E8 E8a emulator to the host computer or user system Operating the E8 E8a emulator debugger Tutorial From starting up the E8 E8a emulator debugger to debugging 2 E8 E8a Additional Document for User s Manual The E8 E8a Additional Document for User s Manual describes content dependent on the MCUs and precautionary notes Example of the E8 E8a emulator connection or interface circuit necessary for designing the hardware Notes on using the E8 E8a emulator Setting the E8 E8a emulator debugger during startup ENESAS ENESAS Section 2 Connecting the Emulator with the User System Before connecting an E8 E8a emulator hereafter referred to as emulator with the user system a connector must be installed in the user system so that a user system interface cable can be connected When designing the user system refer to the connector and recommended circuits shown in th2. User system connector Pin 13 RES pin Figure 4 4 Example of a Reset Circuit 4 Connect Vss and Vcc with the Vss and Vcc of the MCU respectively within the guaranteed range of the microcomputer When the power supply mode is used the power is supplied to the user system Check that the power consumption or voltage of the user system is within the available range of E8 E8a and avoid a problem such as closing of the power supply circuit 5 Connect nothing with N C When the emulator is connected to the user system ground the TEST pin of the MCU MCU TEST Figure 4 5 Emulator and the TEST Pin Note When the emulator is connected ADTRG which is also used as the TEST pin cannot be used ENESAS 4 WARNING In the power supply mode connect the emulator after checking that the power supply circuit on the user system is not closed or the pin number assignments of the user system connector is correct Failure to do so will result in a FIRE HAZARD and will damage the host computer the emulator and the user system 7 Figures 4 6 and 4 7 show the interface circuit in the E8 and E8a emulators respectively Use these figures as references when determining the pull up resistance value ENESAS User system connector Power supply circuit only used for the power supply mode Emulator control circuit 74LVC125A 74LVC125A 3 3 V 2CS2462LC This figure omits the test circuits a
