nPM1300 TWI(I2C) I/F with nRF5x

Hi

At nPM1300 product specification V1.1 page 148(8.1 Schematic)

The control I/F between nPM1300 and nRF5x is TWI(I2C), and there is four signals(SCL, SDA, Reset, INT)

SCL, SDA & INT are usual signals for I2C as I know, so what the purpose for this reset signal?

And this reset action is active by press “SW1”?

Since our SCH don’t have “SW1”, the reset signal connection still need exist? Or can delete?

Also this I2C I/F can only connect to nRF5x P0.xx? Or can connect to P1.xx & P2.xx too?

Thank you

Poki
