4.3.1 Other Functions
Oscillator Pinout
The oscillators are not mapped to the normal PORT functions and their multiplexing are controlled by registers in the System Controller (SYSCTRL).
Oscillator | Supply | Signal | I/O pin |
---|---|---|---|
XOSC | VDDIO | XIN | PA14 |
XOUT | PA15 | ||
XOSC32K | VDDANA | XIN32 | PA00 |
XOUT32 | PA01 |
Serial Wire Debug Interface Pinout
Only the SWCLK pin is mapped to the normal PORT functions. A debugger cold-plugging or hot-plugging detection will automatically switch the SWDIO port to the SWDIO function.
Signal | Supply | I/O pin |
---|---|---|
SWCLK | VDDIO | PA30 |
SWDIO | VDDIO | PA31 |
