nrf52, Any limitation which pins that can run SPI & UART ?

[davman]

Hey guys,

I'm just being very lazy today and I just skimmed the datasheet for <nRF52832_PS_v1.0.pdf> but didn't manage to find if there are any "pin-muxing" limitations that I should be aware of.

Basically I just need to ensure the 6x pins I choose can do SPI & UART. :-)

No there is no such limitation on using pins for SPI or UART. What you need to do is just to take care in your program that the pins that was used for either UART or SPI shouldn't configured for other use that's it.

I do not recommend using NFC pins due to the configuration needed and current leakage problem. The rest are ok.

Perfect, thanks Pavan & Wojtek!

Actually ,I want this "Pin mux Table" too E.g

P0.06 P0.08 can set as uart TX RX,but why P0.15 P0.16 also can be used as TX RX I thought there is a pinmux table that specify P0.15 and P0.16 can set as UART via Peripheral Register
