Section 4 Instruction Features
arithmetic shifts, and logical shifts. or MSB detection instructions and rounding instructions, set
the condition bits like for arithmetic operations.
Arithmetic operations include overflow preventing instructions (saturation operations). When
saturation operation is specified with the S bit in the SR register, the maximum (positive) or
minimum (negative) value is stored when the result of operation overflows.
4.5
The DSP command performs two different types of memory accesses. One uses the X and Y data
transfer instructions (MOVX.W and MOVY.W) while the other uses the single data transfer
instructions (MOVS.W and MOVS.L). Data addressing for these two types of instructions also
differs. Table 4.9 summarizes the data transfer instructions.
