3.3.4.5 RRX
Rotate right with extend moves the bits of the register Rm to the right by one bit. And it copies the carry
flag into bit[31] of the result. See Figure 3.5 (p. 42) .
When the instruction is RRXS or when RRX is used in Operand2 with the instructions MOVS, MVNS, ANDS,
ORRS
, ORNS, EORS, BICS, TEQ or TST, the carry flag is updated to bit[0] of the register Rm.

3.3.5 Address alignment
An aligned access is an operation where a word-aligned address is used for a word, dual word, or
multiple word access, or where a halfword-aligned address is used for a halfword access. Byte accesses
are always aligned.
The Cortex-M3 processor supports unaligned access only for the following instructions:
LDR, LDRT
LDRH, LDRHT
LDRSH, LDRSHT
STR, STRT
STRH, STRHT
All other load and store instructions generate a usage fault exception if they perform an unaligned access,
and therefore their accesses must be address aligned. For more information about usage faults see
Unaligned accesses are usually slower than aligned accesses. In addition, some memory regions might
not support unaligned accesses. Therefore, ARM recommends that programmers ensure that accesses
are aligned. To avoid accidental generation of unaligned accesses, use the UNALIGN_TRP bit in the
Configuration and Control Register to trap all unaligned accesses, see Section 4.3.8 (p. 101) .
3.3.6 PC#relative expressions
A PC#relative expression or label is a symbol that represents the address of an instruction or literal
data. It is represented in the instruction as the PC value plus or minus a numeric offset. The assembler
calculates the required offset from the label and the address of the current instruction. If the offset is too
big, the assembler produces an error.
