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.

Help¶

This option enables the Watchdog Timer driver for NPCX family of processors. Say y if you wish to use watchdog on NPCX MCU.
