34.5 Product Dependencies
In order to use this peripheral, other parts of the system must be configured correctly, as described below.
34.5.1 I/O Lines
Using the USART’s I/O lines requires the I/O pins to be configured using the I/O Pin Controller (PORT).
When the SERCOM is used in USART mode, the SERCOM controls the direction and value of the I/O
pins according to the table below. If the receiver or transmitter is disabled, these pins can be used for
other purposes.
