Question
In 8085A microprocessor, the operation performed by the instruction LHLD 2100H is
Correct answer
(C) (H) arrow M(2101_H), (L) arrow M(2100_H)
Solution
The instruction LHLD addr (Load H and L Direct) in the 8085A microprocessor is a 3-byte instruction that loads the contents of the memory location specified by the 16-bit address into the L register, and the contents of the next consecutive memory location into the H register.For the instruction LHLD 2100H:
1.The content of memory location is moved to the L register: .
2.The content of memory location is moved to the H register: .
This matches option (C).Continue learning with Success Tracker
