Section 3 DSP Operating Unit
The shift amount for the arithmetic shift (PSHA) instruction has a 7-bit field that can represent
values from –64 to +63, but –32 to +32 are valid numbers for the instruction. Also the shift
amount for a logical shift operation has a 6-bit field, but –16 to +16 are valid numbers for the
instruction.
