Typically the data fed to display (single or multiple) is provided for single display at a time. If multiple displays are required scan signal must be additionally provided (according typical dynamic display indication).\hypertarget{index_disp_data_bit_mapping}{}\subsection{Display Segment Bit Mapping}\label{index_disp_data_bit_mapping}
