2.4.5 Address Register Indirect with Predecrement Mode
word. Coprocessors may support decrementing for any operand size up to
255 bytes. If the address register is the stack pointer and the operand size is
pointer aligned to a word boundary.
In the address register indirect with predecrement mode, the operand is in
memory, and the address of the operand is in the address register specified
by the register field. Before the operand address is used, it is decremented
by one, two, or four depending on the operand size: byte, word, or long
byte, the address is decremented by two rather than one to keep the stack
