Table 5-5 lists the combinations of SIZ1, SIZ0, A1, and A0 and the corresponding pattern
of the data transfer for write cycles from the internal multiplexer of the MC68020/EC020 to
the external data bus.

x = Don't care
NOTE: The OP tables on the external data bus refer to a particular byte of the operand that
is written on that section of the data bus.
Table 5-5. MC68020/EC020 Internal to External Data Bus
Due to the current implementation, this byte is output but never used.
