Section 2 CPU
other than A0G and A1G in the word mode, lower half of the register is cleared. When it is A0 or
A1, the data is sign-extended to bits 39 to 32 and lower half of it is cleared. When A0G or A1G is
a destination register in the word mode, data is loaded into 8-bit register, but A0 or A1 is not
cleared. In the longword mode, when a destination register is A0 or A1, it is sign-extended to bits
39 to 32.
Tables 2.3 and 2.4 show the data type of registers used in the DSP instructions. Some instructions
cannot use some registers shown in the tables because of instruction code limitation. For example,
PMULS can use A1 for source registers, but cannot use A0. These tables ignore details of the
register selectability.
