1. Due to muxing constraints, the SPI_NSS is not available as an alternate on this I/O, so this pin is affected by an I/O function
to do the chip selection.
A solder bridge (SB20) is used to disconnect the VREFP to the ARDUINO
• SB20 OFF: VREFP is not connected to the ARDUINO
• SB20 ON: VREFP is connected to the ARDUINO
