Note:
1. All analog pin functions are on peripheral function B. Peripheral function B must be selected to
disable the digital control of the pin.
2. Only some pins can be used in SERCOM I
2
C mode. See the Type column for supported I
2
C
modes.
– Sm: Standard mode, up to 100kHz
– Fm: Fast mode, up to 400kHz
– Fm+: Fast mode Plus, up to 1MHz
– Hs: High-speed mode, up to 3.4MHz
3. These pins are High Sink pins and have different properties than regular pins:
PA12, PA13, PA22, PA23, PA27, PA31, PB30, PB31.
4. Clusters of multiple GPIO pins are sharing the same supply pin.
5. The 49
th
pin of the WLCSP49 package is an additional GND pin.
6. SAM L22N: SERCOM[0:5]. SAM L22G, L22J: SERCOM[0:3].

7.2. Other Functions
7.2.1. Oscillator Pinout
The oscillators are not mapped to the normal PORT functions and their multiplexing is controlled by
registers in the Oscillators Controller (OSCCTRL) and in the 32K Oscillators Controller (OSC32KCTRL).
