Is there specification for the setting timer mode of WTCSR?

Latest Updated:03/23/2009

Question:

It counts the oscillation setting time by using WDT (watchdog timer) when the frequency that uses PLL is changed. At this time, is there specification for the setting of timer mode selection bit (WT/IT#) of watchdog timer control/status register (WTCSR)?

Answer:

It is general to use the interval mode because WDTOVF # signal when the frequency that uses PLL is changed is not used though the setting of the timer mode selection bit can be specified with either interval mode or the watchdog timer mode.
