Hi,
I still have problems understanding the port and pin assignment for peripherals on the nrf54L15.
I need up to three SPIM, one UART and one TWI. That should work, right?
So my only option would be
1x SPIM/UART on P2 ("dedicated pins)"
1x SPIM/UART on P0
2x SPIM/UART on P1
1x TWI on P1?
For TWI, the data sheets (p.633) says "Use GPIO port P1, or dedicated pins on P2", but it does not state, which pins on P2 are dedicated for TWIM.
Hi
Yes, the nRF54L15 supports up to 5 fully featured serial interfaces, so this should be fine.
I'll need to wait for confirmation on this internally, but I think that the TWI pins on P2 that are dedicated are the same as the corresponding UARTE/SPI pins of the same instance, as the serial peripherals share instance IDs with one another. Just remember that the SCL is required to be on a clock pin (marked in red on the pin assignments):
Best regards,
Simon
EDIT: This is a documentation error that will be fixed in future nRF54L15 datasheet versions. There is no TWIM/TWIS on P2 and the text in the instantiation table will be fixed to represent this.
