8085 / 8085A - Direct Addressing

Jump instructions include a 16-bit address as part of the instruction. For example, the instruction JMP 1000H causes a jump to the hexadecimal address 1000 by replacing the current contents of the program counter with the new value 1000H.

Instructions that include a direct address require three bytes of storage: one for the instruction code, and two for the 16-bit address.
