Timing Diagram Of Lhld Instruction In 8085 -

: 5 (Opcode Fetch, Memory Read, Memory Read, Memory Read, Memory Read) T-States : 2. Breakdown of Machine Cycles The timing diagram is divided into five distinct phases: Machine Cycle Description M1 Opcode Fetch 4 T-states Fetches the opcode 2Bh from memory. M2 Memory Read 3 T-states Reads the lower-byte of the 16-bit address ( M3 Memory Read 3 T-states Reads the higher-byte of the 16-bit address ( M4 Memory Read 3 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

Increments the address by 1 and reads data into the . 3. Signal Behavior in the Timing Diagram : 5 (Opcode Fetch, Memory Read, Memory Read,

: The processor increments the address by 1, reads the next byte, and stores it in the H register . M5 Memory Read 3 T-states

Uses the 16-bit address just loaded to read data into the . M5 Memory Read 3 T-states
