To avoid repetition of the same delay instructions, the subroutine technique is used. Delay instructions are written once, separately from the main program, and are called by the main program when needed. The 8085 microprocessor has two instructions to implement subroutines: CALL (call a subroutine), and RET (return to
One use includes passing arguments to assembly functions like this: CALL function_name DB 1,2,3 ;arguments function_name: XTHL MOV A,M ;get argument INX H ;move to next argument XTHL ;now return modified return address to stack, ;also restoring HL contents as well. Other use is to have

(10) Data Transfer Instructions• XTHL• Exchange H–L with top of stack• The contents of L register are exchanged withthe location pointed out by the contents ofthe SP.• The contents of H register are exchangedwith the next location (SP + 1).• Example:
8 May 2015 ADDRESSING MODES & DATA TRANSFER INSTRUCTION OF 8085 MICROPROCESSOR Presented by : Vaibhavi K. Patel (140133103025) : Roshni M. Patel (140133103026) : Chinmaye
Opcode, Operand, Meaning, Explanation. MOV. Rd, Sc. M, Sc. Dt, M. Copy from the source (Sc) to the destination(Dt). This instruction copies the contents of the source register into the destination register without any alteration. Example ? MOV K, L. MVI. Rd, data. M, data. Move immediate 8-bit. The 8-bit data is stored in the
XTHL exchanges HL register with the content of the stack. XTHL followed by RET allows to return to an other address than the one which was previously.
XTHL: - This instruction exchanges H and L with top of stack. The contents of the L register are exchanged with the stack location pointed out by the contents of the stack pointer register. The contents of the H register are exchanged with the next stack location (SP+1); however, the contents of the stack pointer register are not
