Tables 3.14 and 3.15 show the data type of registers used in DSP instructions. Some instructions
cannot use some registers shown in the tables because of instruction code limitations. For
example, PMULS can use A1 as the source register, but cannot use A0. These tables ignore details
of register selectability.
