Software break function
Up to four software breakpoints can be set in the internal ROM area. The number of software
breakpoints that can be set in the RAM area differs depending on the debugger to be used.
Debug monitor function
A memory space for debugging that is different from the user memory space is used during
debugging (background monitor mode). The user program can be executed starting from any
address.
While execution of the user program is aborted, the user resources (such as memory and I/O) can
be read and written, and the user program can be downloaded.
Mask function
Each signal can be masked.
The correspondence with the mask functions of the debugger (ID850NWC) for the N-Wire
emulator (IEV850E1-CD-NW) of NEC Electronics is shown below.
The execution time of the user program can be measured.
Depending on the debugger to be used, whether the peripheral macro operates or is stopped
during a break can be selected.
• Functions that are always stopped during break
• Functions that can operate or be stopped during break (however, each function cannot be
• Peripheral functions that continue operating during break (functions that cannot be stopped)
