This field must be written twice, first with key value 0x55, then 0xAA, for a write operation to be effective. This field always reads
as zero.
Counter bit TBAN is used as watchdog “banned” time frame. In this time frame clearing the WDT timer is forbidden, otherwise a
watchdog reset is generated and the WDT timer is cleared.
0: Select the system RC oscillator (RCSYS) as clock source.
1: Select the 32KHz crystal oscillator (OSC32K) as clock source.
0: The WDT clock is disabled.
1: The WDT clock is enabled.
Counter bit PSEL is used as watchdog timeout period.
This bit is set after any reset.
0: The flash calibration will be redone after a watchdog reset.
1: The flash calibration will not be redone after a watchdog reset.
0: WDT Control Register is not locked.
1: WDT Control Register is locked.
Once locked, the Control Register can not be re-written, only a reset unlocks the SFV bit.
0: The WDT is in basic mode, only PSEL time is used.
1: The WDT is in window mode. Total timeout period is now TBAN+PSEL.
Writing to this bit when the WDT is enabled has no effect.
