(7) Debug monitor function
(8) Mask function
(9) Timer function
(10) Function to select operation/stop of peripheral functions during a break
(11) Open break function
During debugging, a memory space for debugging that differs from the user memory space is used
(background monitor format). The user program can be executed starting from any address.
While execution of the user program is stopped, the user resources (such as memory and I/O) can be read or
written, and the user program can be downloaded.
Signals can be masked.
The mask function of the debugger (ID850QB) for the on-chip debug emulator (QB-V850MINI) and the
corresponding functions are shown below.
The execution time of the user program can be measured.
Depending on the debugger used, whether to operate or stop peripheral functions during a break can be
selected.
• Peripheral functions that always stop during a break
• Peripheral functions for which operation/stop can be selected (however, cannot be selected individually)
• Peripheral functions that continue operating during a break (cannot be stopped)
If a break occurs during on-chip debugging, the specified timer output can be set to a high-impedance state.
By using this function, devices and systems that are driven by timer output can be protected during a break.
