5.Limitations
5.2.3. Limitations on watchdog timer
A monitor program does not reset a watchdog timer. When using a watchdog timer,
close the RAM monitor window and watch window in advance before executing. Do not
generate a memory access by the debugger during executing the user's program.
5.2.4. Oscillation stop detection function
When starting a reset by the oscillation stop detection, the monitor program operates
and may rewrite the user memory. Do not use the oscillation stop detection function.
5.3. Limitation on interrupts
User interrupt vector address
The branch to the interrupt process of the user's program is performed via the monitor
program. Allocate the interrupt vector of the user's program to the following addresses.
Also, the monitor program uses the BRK instruction interrupt. This interrupt cannot be
used on the user's program.
