nRF54L15 I2C INT pin assignment for nPM1300 I2C connection

[Poki Huang]

Hi

Two questions as below

1. About nPM1300 & nRF54L15 I2C connection, at nRF54L15 side, I put SCL/SDA at P1.x group, so INT also need at P1.x group? Or I can put at P0.x group?

2. About below interrupt pin description, this mean port P0 can have max 4 interrupt pins & port P1 have max 8 interrupt pins? 

Thank you

Poki

Hi

Any GPIO can be used as an interrupt with the regular GPIO API, so no real limitations there. The GPIOTE interrupts only have a few interrupts though, and only these can be used for hardware tasks/events.

But for "normal" GPIO interrupts (buttons or generic events) you can configure any GPIO as an interrupt without needing GPIOTE channels.

Best regards,
