Home » ARM and Thumb Instructions » STR (immediate offset) Thumb 32-bit encoding, word, halfword, or byte, –255 to 4095, –255 to 255, –255 to 255, T2. 22 Aug 2008 Many Thumb data process instruction use a 2-address format. – Thumb instruction inserting the appropriate condition code after STR / LDR. ARM code: add R0, R1, R2. Format: Label opcode Rd, Rn, Rm ; comments. Rm can be shifted ARM provides LDR/LDRH/LDRB and STR/STRH/STRHB. Most ARM mnemonics consist of three letters, e.g. SUB, MOV, STR, STM. . Now, as we know, an ARM instruction has 32 bits in which to encode the instruction 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.
