UPD301C Basic Sink Application Example
######################################
Overview
********
The UPD301C Basic Sink Application Example Evaluation Kit (EV11L78A)
is a low-cost evaluation platform for Microchip's UPD301C Standalone
Programmable USB Power Delivery (PD) Controller. This RoHS-compliant
evaluation platform comes in a small form factor and adheres to the
USB Type-C™ Connector Specification and USB PD 3.0 specification.

:zephyr_file:`boards/microchip/ev11l78a/ev11l78a_defconfig`.
Serial Port
===========
The SAMD20 MCU has 6 SERCOM based USARTs. One of the USARTs
(SERCOM1) is available on the Debug/Status header.
SPI Port
========
The SAMD20 MCU has 6 SERCOM based SPIs. One of the SPIs (SERCOM0)
is internally connected between the SAMD20 core and the UPD350.
I²C Port
========
The SAMD20 MCU has 6 SERCOM based I2Cs. One of the I2Cs (SERCOM3)
is available on the Debug/Status header.
