BQ24271 I2C Interface protocol

Hi All,

Has anyone accessed this device via the I2C bus. I cannot find any information relating to how to use the interface for accessing the registers - doesn't appear to be covered in the datasheet.

What I need to know is this:-

Is the first byte following the I2C address the internal register address.

Does this auto increment - ie if I read 2 bytes is the data from adjacent registers.

To read a register, must I write the address word first, or do I just read out the whole block.

- Very surprised I can't find this info, so if it is there please direct me!

(Otherwise I assume people just use this in default mode).
