The data transfer instructions are divided into two groups, double data transfers and single data
transfers. Double data transfers can be combined with DSP operation instructions to perform DSP
parallel processing. The parallel processing instructions are 32 bits in length, and the double data
transfer instructions are incorporated into their A fields. Double data transfers that are not parallel
processing instructions are 16 bits in length, as are the single data transfer instructions.
The X memory and Y memory can be accessed simultaneously in parallel in double data transfers.
One instruction each is designated from among the X and Y memory data accesses. The Ax
pointer is used to access X memory; the Ay pointer is used to access Y memory. Double data
transfers can only access X, Y memory.
