nRF54l15 TWI pin configuration

From what I understood, it is not that the pins don't exist on P2, the dedicated pin they are mentioning in there is the "dedicated clock pins" on P2. The SCL needs to be a clock pin, and per the recommendation the SDA pin needs to be close to the SCL pin to avoid propagation delays.

Hi So does this mean that p2 pins don't exist here?

Hello Lvaylo,

Unlike SPI and UARTE which have specific cross-domain pin assignments on P2, the documentation doesn't show any dedicated cross-domain pins for TWIM on P2.

Thank you for clearing that up Kazi.

Also since P2 has dedicated pins for SPI and UARTE, does that mean it also has dedicated pins for the TWIM or is it that any pin would work for the SDA?

Best,

Ivaylo

Hello lavylo,

Thanks for pointing this out. I have talked internally. Only SCL pin needs to be connected to CLK pin.

The following information is not correct, and it will be removed on next version of documentation.
