29.4 Signal Description

Using the SERCOM I/O lines requires the I/O pins to be configured using port configuration (PORT).

The SERCOM has four internal pads, PAD[3:0], and the signals from I²C, SPI and USART are routed through these SERCOM pads through a multiplexer. The configuration of the multiplexer is available from the different SERCOM modes.

Refer to the respective SERCOM mode chapters for additional information.
