[1] The power-on reset circuit resets the I2C-bus logic with VDD < VPOR and set all I/Os to logic 1 (with current source to VDD).
[2] Each bit must be limited to a maximum of 25 mA and the total package limited to 400 mA due to internal busing limits.
[3] The value is not tested, but verified on sampling basis.
