GATE ECE 1996 | Instruction Set and Programming with 8085 Question 26 | Microprocessors

GATE ECE 1996

MCQ (Single Correct Answer)

-0.3

The following sequence of instructions are executed by an 8085 microprocessor:
1000: LXI SP< 27FF
1003: CALL 1006
1006: POP H

The contents of the stack pointer (SP) and the HL register pair on completion or execution of these instructions are.

SP= 27FF, HL = 1003

SP= 27FD, HL = 1003

SP= 27FF, HL = 1006

SP= 27FD, HL = 1006
