Does NRF52840 TWI peripheral can handle slave's I2C clock streaching.

Hi,

Can you confirm if TWI is supporting I2C clock streaching? Or and workaround to handle such a case.

As in attached picture is slave device requirements. Slave device stays in deep sleep mode and awakes on I2C address match but it requires some time to turn ON Eerything else.so it keeps I2C SCL low (clock streaching).

In such a situation TWI throws i2c internal error.

Hi,

Clock stretching is supported by the TWIM peripheral. Which function is throwing the error and exactly what error is returned? What parameters do you pass to the function?
