If the mode is switched from/to watchdog timer to/from interval timer, while the WDT is
operating, errors could occur in the operation. Software must stop the watchdog timer (by clearing
the TME bit to 0) before switching the mode.
13.6.6
Inputting the RESO output signal to the RES pin of this LSI prevents the LSI from being
initialized correctly; the RESO signal must not be logically connected to the RES pin of the LSI.
To reset the entire system by the RESO signal, use the circuit as shown in figure 13.8.
