.. option:: 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.

Help
====

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