a.MOV A, B:
register addressing mode
MOV is a mnemonic, which stands for “MOVe”. In this instruction 8-bit data value in register r2 will be moved to the 8-bit register r1.
b.MVI, 05H:
MVI is a mnemonic, which actually means “Move Immediate”. With this instruction,we can load a register with an 8-bitsor 1-Bytevalue.
immediate addressing mode
c.LHLD, 3000H:
absolute addressing mode
LHLD is a mnemonic that stands for Load HL pair using Direct addressing from memory location whose 16-bit address is denoted as a16.
d. XCHG:
implied addressing mode
XCHG, which stands for eXCHanGe. This is an instruction to exchange contents of HL register pair with DE register pair.
e. CMP B:
implicit addressing mode
This instruction is used to compare contents of the Accumulator with given register R. The result of compare operation will be stored in the Temp register.
