XMEGA D4
27. Pinout and Pin Functions
The pinout of XMEGA D4 is shown in ”Pinout/Block Diagram” on page 3. In addition to general
I/O functionality, each pin may have several functions. This will depend on which peripheral is
enabled and connected to the actual pin. Only one of the alternate pin functions can be used at
time.
