8085 Program to ADD 16-bit number in memory locations
Add the 16-bit number in memory locations 4000H and 4001H to the 16-bit number
in memory locations 4002H and 4003H. The most significant eight bits of the two
numbers to be added are in memory locations 4001H and 4003H. Store the result in
memory locations 4004H and 4005H with the most significant byte in memory
For following program we have change address to following :
LHLD 0700 : 3 byte instruction, it stands for Load HL pair using Direct addressing. This instruction will load 16-bits data from memory location 0700 to HL pair.
XCHG : 1 byte instruction, stands for exchange. This instruction will exchange data between HL pair and DE pair. Data of H register will swapped with D register and data of L register will swapped with E register.
LHDL : This instruction will load 16-bits data from memory location 0702 to HL pair.
DAD D : 1 byte instruction, it stands for Double ADD. This command will add values of DE pair with values of HL pair.
SHLD 0704 : 3 byte instruction, it stands for Store HL pair using Direct addressing. This command will store 16 bits data from HL pair to 0704 memory location.
HLT – This command is use to put microprocessor on halt.
