Note Because the simulator s execution time measurement is calculated using the number of cycles described above it includes some error when compared with the actual chip s execution time e WAIT Executed as an NOP instruction Other instructions operate the same as those of the actual MCU e INT INTO UND BRK As with the actual MCU these instructions generate interrupts The INTO instruction only generates an interrupt when the O flag is 1 2 3 2 Resetting e The SFR area is nonexistent in the debugger so the initialization as in the actual chip is not performed e The cycle count is initialized to 0 Resetting is performed in the same way as the actual MCU A reset is also performed when the debugger starts The value 000F000016 is set in the reset vector immediately after starting The program counter is therefore set to F000016 immediately after the debugger starts 27 2 3 3 Memory Memory Space There is no processor mode If mapped for memory the whole 1MB of memory from 00000h to FFFFFh can be read from and written to as RAM Note however that in the initial state memory between 10000h and EFFFFh is not secured and an error will result if an attempt is made to access this part of memory If this occurs while a program is running the program will stop with an illegal memory access error Use the map function described later to map this part of memory Memory Structure and Initial Values Immediately after Sta
