Pin assignments for NRF5340

[Nivethitha]

Hi,

In nrf5340 pin assignment for SPIM2 is given,

How to select which pin to use if we need to use SPIM1/3?

How to know Pin function and all its alternate functions for particular pin?

Hi,

I think you're looking at an outdated product specification that contained an error, if you look at the current product specification, you can see that it mentions SPIM4 instead.

Thus, this restriction is not relevant for SPIM1-3,

Thanks Jared.

What if I want to use 2 SPIM ? How to select the pins? In pin assignments only SPIM4 is given?

Im also using the QSPI.

Hi,

You can use any GPIOs for SPIM except for SPIM4 where we recommend using the dedicated SPIM pins.

PO.11 - CSB

2) SPIM2(8 Mbps)

P0.19 - MOSI
P1.05 - MISO
P1.04 - CS

3) I2C1 (High speed)
