For this reason the real time emulation cannot be performed When the real time emulation is necessary during the program operation firstly disable the automatic update in the watch window or fix the display in the memory window so that the memory access will not occur during execution When the E8 does not supply power to the user system the E8 emulator consumes the power voltage of the user system from several mA to over 10 mA This is because the user power supply drives one 74LVC125A to make the communication signal level match the user system power supply voltage When debugging the flash memory is frequently re written by the E8 emulator Therefore do not use an MCU that has been used for debugging Also as the program for the E8 emulator is written into the MCUs while debugging do not save the contents of the MCU s flash memory that have been used for debugging or use them as the ROM data for products NMI interrupt If NMI interrupts are to be used be sure to take the necessary measures before executing the user program by for example disabling automatic updates of the watch window and freezing the display of the memory window in order to ensure that no memory accesses will occur during user program execution If an NMI interrupt occurs while the user program remains idle or when memory contents are referenced or changed during user program execution device operation becomes uncontrollable by the E8 emulator 15 ENESAS
