Section 4 Instruction Features
4.5.2
The DSP command has single data transfer instructions (MOVS.W and MOVS.L) that load data
to DSP registers and store data from DSP registers. With these instructions, the R2–R5 registers
are used as address registers (As) for single data transfers.
There are four types of data addressing for single data transfer instructions.
The address pointer uses the R8 register as its index register (Is). Figure 4.2 shows the single data
transfer addressing.

Address registers with no update: The As register is the address pointer. It is not updated.
Addition index register addressing: The As register is the address pointer. The value of the Is
register is added to the As register after data transfer (post-increment).
Increment address register addressing: The As register is the address pointer. +2 or +4 is added
to it after data transfer (post-increment).
Decrement address register addressing: The As register is the address pointer. –2 or –4 (or +2
or +4) is added to it before data transfer (pre-decrement).
+2 (INC)
+0 (No update)
Notes: 1.
Single Data Addressing
2.
Adder added for DSP processing
All three addressing methods (increment, index register addition (Ix, Iy), and
no update) are post-increment methods. To decrement the address pointer, set
the index register to –2 or –4.
