Timing Diagram Of Lhld Instruction In 8085 File

To visualize the diagram, consider the following behavior of the system bus during these 16 T-states:

: 3 Bytes (Byte 1: Opcode, Byte 2: Lower-order address, Byte 3: Higher-order address) Function : Timing Diagram Of Lhld Instruction In 8085

: Goes high during the first T-state ( T1cap T sub 1 ) of every machine cycle to latch the lower address ( Higher Address Bus ( To visualize the diagram, consider the following behavior

(H)←[[adr+1]]open paren cap H close paren left arrow open bracket open bracket a d r plus 1 close bracket close bracket (Content of memory address moves to H) To visualize the diagram

(L)←[[adr]]open paren cap L close paren left arrow open bracket open bracket a d r close bracket close bracket (Content of memory address moves to L)

: The processor increments the address by 1, reads the next byte, and stores it in the H register .

, it decodes the instruction and realizes it needs a 16-bit address.
