Signal Supply I/O pin
SWO VDDIO PB30, PC27
6.2.4 Supply Controller Pinout
The outputs of the Supply Controller (SUPC) are not mapped to the normal PORT functions. They are
controlled by registers in the SUPC.
Table 6-6. SUPC Pinout
Signal I/O pin
OUT0 PB01
OUT1 PB02
Note:  If the RTC is enabled to use the pins shared with the SUPC, the RTC will have higher priority.
6.2.5 RTC Pinout
The pins used for Tamper Detection by the Real Time Counter (RTC) are not mapped to the regular
PORT functions. These pins and their multiplexing is controlled by register settings of the RTC. If many
pins of the tamper detection feature is not used by the RTC, then the pin could be used for other I/O
functions, by ensuring the corresponding TAMPCTRL.INACT function is disabled.
Table 6-7. RTC Pinout
RTC Signal I/O Pin
IN0 PB00
IN1 PB02
IN2 PA02
IN3 PC00
IN4 PC01
OUT PB01
Important:  If Supply Controller (SUPC) and RTC are configured to drive pin PB1 or pin PB2,
then the RTC has priority.
6.2.6 SERCOM I

C Configurations
The SAM D5x/E5x has up to eight instances of the serial communication interface (SERCOM) peripheral.
All instances support USART, including RS485 and ISO7816, SPI and I²C protocols. The following table
lists the I²C pins location.
