Note that with external termination, address signals do not change. With internal
termination, Figure 18-20, A[1:0] increment for the same longword transfer.
18.5 Misaligned Operands
Because operands, unlike opcodes, can reside at any byte boundary, they are allowed to be
misaligned. A byte operand is properly aligned at any address, a word operand is
misaligned at an odd address, and a longword is misaligned at an address not a multiple of
four. Although the MCF5307 enforces no alignment restrictions for data operands
(including program counter (PC) relative data addressing), additional bus cycles are
required for misaligned operands.
