externally, the SDAH line becomes fully I
serial data line is advantageous in COG applications because here the track resistance from the SDAHOUT pad to
the system SDAH line can be significant and a potential divider can be generated by the bus pull-up resistor and the
ITO track resistance. It is possible that during the acknowledge cycle the OM6208 will not be able to create a valid
logic 0. By splitting the SDAH input from the SDAHOUT output the device could be used in a mode that ignores the
acknowledge bit. Therefore in COG applications where the acknowledge cycle is required, it is necessary to minimize
the track resistance from the SDAHOUT pad to the system SDAH line to guarantee a valid logic 0. When SDAHOUT
