1. Debugging in stop mode or wait mode When in stop mode or wait mode the program cannot be stopped by the E8 emulator If you attempt to stop the program in stop or wait mode the emulator will not control the MCU Do not operate windows until the program stops at the breakpoint by setting the breakpoint at the line of the program where the stop mode or the wait mode is cancelled When using stop mode or wait mode in the user program disable the automatic update in the watch window or fix the display in the memory window before running the program so memory accesses do not occur during an execution Peripheral I Os during a halt During a user program halt interrupts are not accepted although peripheral I Os continue to run For example a timer interrupt is not accepted although the timer continues to count when a user program is stopped by a break after the timer started REJ10J1350 0100 Rev 1 00 Aug 01 2007 Page 17 of 26 tENESAS E8 Emulator Section 6 Notes on Using the E8 Emulator 17 Exceptional step execution a Software interrupt instruction Step execution cannot be performed in the internal processing of instructions undefined overflow BRK and INT which generate a software interrupt continuously in the program Example INT instruction NOP NOP INT 3 nes Passes through if the STEP execution is carried out JMP MAIN INT 3 NOP lt lt Program should be stopped at this address NOP NOP REIT b INT instruc2.
