CONFIG_UART_NPCX¶

Nuvoton NPCX embedded controller (EC) serial driver

Type: bool

Help¶

Enable support for NPCX UART driver.

Help¶

Enable support for NPCX UART driver. In NPCX9 series, it includes 4
modules which support full-duplex asynchronous receiver-transmitter
with 16-byte transmit and receive buffers.

with 16-byte transmit and receive buffers.

Help¶

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