Data Transfer Group Instruction Set of 8085 Microprocessor

Data Transfer Group of 8085 Microprocessor

    • MOV r1, r2
      • This means the data of register - 2 will move to register - 1
                                        Example - MOV A, B
    • MOV r, M
      • This means the data stored in ((H - L)) will move to specified register.
                                        Example - MOV B, M
    • MOV M, r
      • This means the data in specified register will move to ((H-L)).
                                        Example - MOV M, B
    • MVI r, data
      • This means the given data will move to specified register immediately.
                                        Example - MVI B, 05
    •  MVI M, data 
      • This means the given data will move to ((H-L)) pair register immediately.
                                        Example - MVI M, 05
    • LXI rp, data

    • LHLD addr 
      • Data in given address will load into register 'L' and data in next address of given address will load into register 'H'.
        • Example - LHLD 4200  // This is a command//
                                                           (4200) ⇢ L
                                                           (4201) ⇢ H
    • SHLD addr
      • Data in register 'L' will load into the given address and data in register 'H' will load into the next address of given address
        • Example -  SHLD 4200 //This is a Command//
                                                           L ⇢   (4200) 
                                                           H ⇢   (4201)
    • LDAX rp 
      • The register pair points to a memory location. The data in that memory location will copy to Accumulator.
                                    Example - LDAX B
                                                      ((BC)) ⇢ (A)
    • STAX rp
      • The data in Accumulator will copy to the memory location pointed by register pairs.
        • Example - STAX B
                                                        (A) ⇢  ((BC))
    • XCHG 
      • The contents in HL and DE pair will exchange.
        • Example - HL - 1234
                                                          DE - 4561 
                                                    After execution of the instruction, the result is 
                                                          HL - 4561
                                                          DE - 1234

Pin Diagram of 8085A Microprocessor and working functions of each pin (Study Notes)

Pin Diagram of 8085A Microprocessor  Diagram: Pin Diagram of 8085 Microprocessor Functional of Each Pin (Briefly): 👉A 8 – A 15 (Output): These are address bus and used for the eight most significant bits of the memory address or eight bits i/o address. 👉 AD 0 – AD 7   (Both Input and Output): Thses are time multiplexed address/data bus that is served dual purpose. They are used for the LSB (Least Significant Bits) 8 bits of memory address and data during other time. 👉ALE (Output): It is abbreviated as Address Latch Enable. It goes high when 8 lower bits of address is latched. 👉IO/M* (Output): It is a status signal which distinguishes whether the address is for i/o or memory. When it goes high, the address bus is for an i/o device. And when it goes low, the address is for memory location because M is an active low signal. 👉S 0 , S 1 (Ouput): These are status signal send by microprocessor to distinguish various types of operation. S 0 S 1 O...
