3.2.2 Address Registers
MC68F375
REFERENCE MANUAL
Each address register and stack pointer is 32 bits wide and holds a 32-bit address.
Address registers cannot be used for byte-sized operands. Therefore, when an
address register is used as a source operand, either the low-order word or the entire
long-word operand is used, depending upon the operation size. When an address reg-
ister is used as the destination, the entire register is affected, regardless of the opera-
tion size. If the source operand is a word size, the operand is sign-extended to 32 bits.
Address registers are used primarily for addresses and to support address computa-
tion. The instruction set includes instructions that add to, subtract from, compare, and
move the contents of address registers.
