2.6.3
The instructions in this class are provided to reduce the program code size for DSP operations. All
the new instructions in this class have a 16-bit code length. Instructions in this class are divided
into two groups: single data transfer instructions and double data transfer instructions. The
operand flexibility of the double data transfer instructions is the same as with the A field in
parallel instruction class data transfer instructions described in section 2.6.4, DSP Operation
Instruction Set. However, conditional load instructions cannot be used with these 16-bit
instructions. In single transfer, the Ax pointer and two address pointers (R2 and R3) are used as
the As pointer, but the Ay pointer is not used. Tables 2.27 and 2.28 list the single and double data
transfer instructions.
With double data transfer group instructions, X memory and Y memory can be accessed in
parallel. The Ax pointer can only be used by X memory access instructions, and the Ay pointer
only by Y memory access instructions. Double data transfer instructions can only access the on-
chip X and Y memory areas. Single data transfer instructions use a 16-bit instruction code, and can
access any memory address space.
Rn (n = 2 to 7) registers are normally used as the Ax, Ay, and As pointers. The pointer names
themselves can be changed with the assembler rename function. The following renaming scheme
is recommended.
R2:As2, R3:As3, R4:Ax0 (As0), R5:Ax1 (As1), R6:Ay0, R7:Ay1, R8:Ix(Is), R9:Iy
