2.4.2
Two different memory accesses are made with DSP instructions. The two kinds of instructions are
X and Y data transfer instructions (MOVX.W, MOVY.W) and single data transfer instructions
(MOVS.W, MOVSL). The data addressing is different for these two kinds of instruction. An
overview of the data transfer instructions is given in table 2.13.
Table 2.13 Overview of Data Transfer Instructions
X/Y Data Addressing: With DSP instructions, the X and Y data memory can be accessed
simultaneously using the MOVX.W and MOVY.W instructions. Two address pointers are
provided for DSP instructions to enable simultaneous access to X and Y data memory. Only
pointer addressing can be used with DSP instructions; immediate addressing is not available.
Address registers are divided into two, with register R4 or R5 functioning as the X memory
address register (Ax), and register R6 or R7 as the Y memory address register (Ay). The following
three kinds of addressing can be used with X and Y data transfer instructions.
1. Non-update address register addressing:
2. Addition index register addressing:

The Ax and Ay registers are address pointers. They are not updated.
The Ax and Ay registers are address pointers. After a data transfer, the value of the Ix or Iy
register is added to each (post-increment).
