WINCTRL
STATUS
CTRL
• Bit 0 – SYNCBUSY: Synchronization Busy Flag
This flag is set after writing to the CTRL or WINCTRL registers and the data are being synchro-
nized from the system clock to the WDT clock domain. This bit is automatically cleared after the
synchronization is finished. Synchronization will take place only when the ENABLE bit for the
Watchdog Timer is set.
