Timing Diagram Of Lhld Instruction In 8085 -

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)

, it decodes the instruction and realizes it needs a 16-bit address. Timing Diagram Of Lhld Instruction In 8085

: The PC places the address on the bus; ALE latches it. The processor fetches 2Bh . In T4cap T sub 4 The (Load H and L registers direct) instruction

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