The 8085 Machine Language:
• The 8085 (from Intel) is an 8-bit microprocessor. – The 8085 uses a total of 246 bit patterns to form its instruction set. – These 246 patterns represent only 74 instructions.
• The reason for the difference is that some (actually most) instructions have multiple different formats. – Because it is very difficult to enter the bit patterns correctly, they are usually entered in hexadecimal instead of binary.
• For example, the combination 0011 1100 which translates into “increment the number in the register called the accumulator”, is usually entered as 3C.
