NOTES:
1. Operands in parentheses are ignored by the MC68340 during read cycles.
2. A 3-byte to byte transfer does occur as the second byte transfer of a long-word to byte port transfer.
Figure 3-2. MC68340 Interface to Various Port Sizes
3.2.2 Misaligned Operands
In this architecture, the basic operand size is 16 bits. Operand misalignment refers to
whether an operand is aligned on a word boundary or overlaps the word boundary,
determined by address line A0. When A0 is low, the address is even and is a word and
byte boundary. When A0 is high, the address is odd and is a byte boundary only. A byte
operand is properly aligned at any address; a word or long-word operand is misaligned at
an odd address.
At most, each bus cycle can transfer a word of data aligned on a word boundary. If the
MC68340 transfers a long-word operand over a 16-bit port, the most significant operand
word is transferred on the first bus cycle, and the least significant operand word is
transferred on a following bus cycle.
The CPU32 restricts all operands (both data and instructions) to be aligned. That is, word
and long-word operands must be located on a word or long-word boundary, respectively.
The only type of transfer that can be performed to an odd address is a single-byte
transfer, referred to as an odd-byte transfer. If a misaligned access is attempted, the
CPU32 generates an address error exception, and enters exception processing. Refer to
Section 5 CPU32 for more information on exception processing.
3.2.3 Operand Transfer Cases
The following cases are examples of the allowable alignments of operands to ports.
3.2.3.1 BYTE OPERAND TO 8-BIT PORT, ODD OR EVEN (A0 = X). The MC68340
drives the address bus with the desired address and the SIZx pins to indicate a single-
byte operand.
