XMEGA A4
Not recommended for new designs -
Use XMEGA A4U series
30. Pinout and Pin Functions
The pinout of XMEGA A4 is shown in ”P(pán)inout/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.
30.1
Alternate Pin Functions Description
The tables below shows the notation for all pin functions available and describe their functions.
30.1.1
Operation/Power Supply
30.1.2
Port Interrupt functions
30.1.3
Analog functions
30.1.4
Timer/Counter and AWEX functions
VCC
Digital supply voltage
AVCC
Analog supply voltage
GND
Ground
SYNC
Port pin with full synchronous and limited asynchronous interrupt function
ASYNC
