IO_SUPPLY, VIO, SCLK and SDATA pins

[Pema]

Hi,

The above pins are connected to test points in the ref schematic but stated as Nordic reserved in the pin description. Should I connect them to test points or can I leave them open?

Hi Peter

VIO, SCLK and SDATA are used for RFFE control inside the SiP, and should alongside IO_SUPPLY still be considered as reserved pins. Leave them open.

Best regards,

Simon
