CONFIG_WDT_NPCX

Nuvoton NPCX embedded controller (EC) Watchdog Timer driver

Type: bool

Help

Enable support for NPCX Watchdog driver. Besides watchdog
functionality, it also provides the protection mechanism over software
execution. After setting the configuration registers, the software can
lock it to provide a higher level of protection against subsequent
erroneous software action. Once a section of the TWD is locked, only
reset or the unlock sequence releases it.
