3.2.2 DSP Data Addressing
This LSI has two types of memory access instructions: one type is X and Y data transfer
instructions (MOVX.W and MOVY.W), and the other is single data transfer instructions
(MOVS.W and MOVS.L). Data addressing of these two types of instruction are different. Table
3.18 shows a summary of DSP data transfer instructions.
