To visualize the diagram, consider the following behavior of the system bus during these 16 T-states:
Uses the 16-bit address just loaded to read data into the . M5 Memory Read 3 T-states
: The processor reads the two-byte address from the memory locations immediately following the opcode.
The (Load H and L registers direct) instruction in the 8085 microprocessor is a 3-byte instruction that loads the contents of a specific 16-bit memory address into the H-L register pair . It is one of the most complex instructions in terms of timing, requiring 5 machine cycles and 16 T-states to complete. 1. Instruction Overview Opcode : 2Bh (for LHLD)
: The processor places the 16-bit address it just "learned" onto the address bus. It reads the byte at that location and stores it in the L register .
