A bit operand is specified by a base address that selects one byte in memory
The data types supported in memory by the MC68030 are bit and bit field
2-2. Note that all of these data types can be accessed at any byte address.
Coprocessors can implement any data types and lengths up to 255 bytes.

does not require data to be aligned on word boundaries (refer to Figure
2-2), but the most efficient data transfers occur when data is aligned on the
same byte boundary as its operand size. However, instruction words must
data; integer data of 8, 16, or 32 bits; 32-bit addresses; and BCD data (packed
and unpacked). These data types are organized in memory as shown in Figure
For example, the MC68881/MC68882 floating-point coprocessors support
memory accesses for quad-word-sized items (double-precision floating-point
