3.5.12
The DSP unit of this LSI provides additional two independent registers, MACL and MACH, in
order to support CPU standard multiply/MAC operations. They can be also used as temporary
storage registers by local data move instructions between MACH/L and other DSP registers.
Figure 3.22 shows the flow of seven local data move instructions. Table 3.33 shows the variation
of this type of instruction.
Table 3.33 Variation of Local Data Move Operations
This instruction is very similar to other transfer instructions. If either the A0 or A1 register is
specified as the destination operand of PSTS, the signed bit is sign-extended and copied into the
corresponding guard-bit parts, A0G or A1G. The DC bit in DSR and other condition code bits are
not updated regardless of the instruction result. This instruction can operate as a conditional. This
instruction can operate with MOVX and MOVY in parallel.
