Connecting to the I²C Interface

Four different FLEXCOM interfaces, with seven possible configurations (configured in TWI mode), and one pure TWI
Interface are available on the ATSAMA5D27-WLSOM1 module.

The Flexible Serial Communication Controller (FLEXCOM) offers several serial communication protocols that are
managed by the three submodules USART, SPI, and TWI.
