LD (DE),
Stores the contents of register A in the memory specified by register pair DE.
Example: When DE = 205Ch and A = 00h,
LD (DE) , A ; (205Ch) ← 00h
LD (HLI),
Stores the contents of register A in the memory specified by register pair HL and simultaneously
increments the contents of HL.
Example: When HL = FFFFh and A = 56h,
LD (HLI), A ; (0xFFFF) ← 56h, HL = 0000h
LD (HLD),
Stores the contents of register A in the memory specified by register pair HL and simultaneously
decrements the contents of HL.
Example: HL = 4000h and A = 5h,
