External Bus Interface
The MPC561/MPC563 performs operand transfers through its 32-bit data port. If the transfer is controlled
by the internal memory controller, the MPC561/MPC563 can support 8- and 16-bit data port sizes.
The bus requires that the portion of the data bus used for a transfer to or from a particular port size be fixed.
A 32-bit port resides on DATA[0:31], a 16-bit port must reside on DATA[0:15], and an 8-bit port must
reside on DATA[0:7]. The MPC561/MPC563 always tries to transfer the maximum amount of data on all
bus cycles. For a word operation, it always assumes that the port is 32 bits wide when beginning the bus
cycle.

Word accesses require address bits 30 – 31 to equal zero
Burst accesses require address bits 30 – 31 to equal zero
OP0 is the most-significant byte of a word operand and OP3 is the least-significant byte.
The two bytes of a half-word operand are either OP0 (most-significant) and OP1 or OP2
(most-significant) and OP3, depending on the address of the access.
The single byte of a byte-length operand is OP0, OP1, OP2, or OP3, depending on the address of
the access.
