Notes: 1. Pin mapping of all TC0 can optionally be moved to high nibble of port. Refer to Pin Remap register in I/O Ports in the XMEGA AU Manual.

2. If TC0 is configured as TC2 all eight pins can be used for PWM output. Refer to Pin Remap register in I/O Ports in the XMEGA AU Manual..

3. Pin mapping of all USART0 can optionally be moved to high nibble of port. Refer to Pin Remap register in I/O Ports in the XMEGA AU Manual..

4. Pins MOSI and SCK for all SPI can optionally be swapped.Refer to Pin Remap register in I/O Ports in the XMEGA AU Manual.

5. CLKOUT can optionally be moved between port C, D and E and between pin 4 and 7. Refer to CLKEVOUT register in I/O port configuration in the XMEGA AU

Manual.

6. EVOUT can optionally be moved between port C, D and E and between pin 4 and 7. Refer to CLKEVOUT register in I/O port configuration in the XMEGA AU

Manual.
