WebMay 31, 2024 · LD (ir + d), r where r is an 8-bit register, ir is a index register (IX or IY) and d is a signed byte displacement (-128 to 127). All indexed addressing instructions have at least two op-codes. When dealing with the IX register the first op-code is always 0xDD and 0xFD when using the IY register. The binary format is the following WebLDR loads a 32-bit constant (LDRH (halfword): 16 bit, LDRB (byte): 8 bit) from memory into the specified target register (r0 in your example). Since 32-bit constants cannot be encoded in 32-bit opcodes (or 16-bit for Thumb instructions), the assembler stores the constant in the text segment close to the referencing instruction and then references the value using …

WebLDR instructions load a register with a value from memory. STR instructions store a register value into memory. The memory address to load from or store to is at an offset from the register Rn. The offset is specified by the register Rm and can be shifted left by up to 3 bits using LSL. The value to load or store can be a byte, halfword, or word.
