.. title:: I2C_NPCX

.. option:: CONFIG_I2C_NPCX

*Nuvoton NPCX embedded controller (EC) I2C driver*

Type: ``bool``

Help
====

Enable support for NPCX I2C driver. The NPCX SMB/I2C modules provides
full support for a two-wire SMBus/I2C synchronous serial interface.
Each interface is a two-wire serial interface that is compatible with
both Intel SMBus and Philips I2C physical layer. There are 8 SMBus
modules and 10 buses in NPCX7 series.

Help
====

This option enables the I2C driver for NPCX family of
processors.
Say y if you wish to use I2C modules on NPCX MCU.
