8362E–AVR–01/12

XMEGA A3BU

Notes: 1. Pin mapping of all TC0 can optionally be moved to high nibble of port.

2. If TC0 is configured as TC2 all eight pins can be used for PWM output.

3. Pin mapping of all USART0 can optionally be moved to high nibble of port.

4. Pins MOSI and SCK for all SPI can optionally be swapped.

5. CLKOUT can optionally be moved between port C, D and E and between pin 4 and 7.

6. EVOUT can optionally be moved between port C, D and E and between pin 4 and 7.
