(3) System control instructions
The DSR, A0, X0, X1, Y0, and Y1 registers in the DSP unit can also be used as the CPU system
registers. Accordingly, data transfer operations between these DSP system registers and general
registers or memory can be executed by the STS and LDS instructions. These DSP system
registers can be treated as the CPU system register such as PR, MACH and MACL and can use the
same addressing modes.
