Does nRF52840 support multi-master TWI (I2C)?

The nRF52840 supports 2 Master/Slave instances.

Is it possible to configure the nRF52840 as a Master when connected to an I2C bus that has another Master present?

  • Hi,

    Thank you for the quick response.

    I did see that statement but took it to only apply to the circuit diagram shown - hence the term "This TWIM … ".

    Elsewhere the datasheet shows that the nRF52 supports two TWI instances where one can be a slave and one a master.

    I don't think that they could both be enabled if mapped to the same pins, but could I not map them to different pins and connect those to the same bus?
