- SERCOM4 is internally connected to the AT86RF212B.
- The number of X- and Y-lines depends on the configuration of the device, as some I/O lines can be configured as either X-lines or Y-lines. Refer to Multiplexed Signals for details. The number in the Configuration Summary is the maximum number of channels that can be obtained.
- The number of Y-lines depends on the configuration of the device, as some I/O lines can be configured as either X-lines or Y-lines. The number given here is the maximum number of Y-lines that can be obtained.
