Answer» Intel 8085 handles 8 bit of data as it is an 8 bit microprocessor. It is designed to process 8 bit of data at a time. If a 16 bit data has to be stored then they are stored in consecutive memory locations. There are various ways to specify data for an instruction: 8 bit or 16 bit data may be directly given in the instruction. E.g. ADI 07H, LXI 7051H etc. The address of the memory location or I/O devices may be given in the instruction itself. Ex LDA 8582H, IN 02H etc. In some instructions only one register is specified. Ex ADD B In some instructions we write two registers. Ex MOV D,E In some instructions the data is implicit or implied. Ex CMA, RRC, RAL.
