3.1
Register operands are always longwords (32 bits). When data in memory is loaded to a register
and the memory operand is only a byte (8 bits) or a word (16 bits), it is sign-extended into a
longword when stored into a register.
3.2
Memory data formats are classified into bytes, words, and longwords. Byte data can be accessed
from any address, but an address error will occur if you try to access word data starting from an
address other than 2n or longword data starting from an address other than 4n. In such cases, the
data accessed cannot be guaranteed. The hardware stack area, which is referred to by the hardware
stack pointer (SP, R15), uses only longword data starting from address 4n because this area stores
the program counter (PC) and status register (SR). See the hardware manual for more information
on address errors.
Byte data is arranged as shown below for products with a built-in little endian function. To
determine whether a specific product supports little endian operation, refer to the corresponding
hardware manual.
