2.3
2.3.1
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.
2.3.2
Byte, word, and longword data formats are used. Memory can be accessed in 8-bit bytes, 16-bit
words, or 32-bit longwords. A memory operand of fewer than 32 bits is stored in a register in
sign-extended or zero-extended form.
A word operand should be accessed starting from a word boundary (2-byte even address: address
2n), and a longword operand from a longword boundary (4-byte even address: address 4n). If this
rule is not observed, an address error will occur. A byte operand can be accessed from any
address.
Only big-endian byte order can be selected for the data format.
Data formats in memory are shown in figure 2.4.
