Details of the status register (SR) when STC/LDC instructions are used are shown below.
1. When the DSP is not operating, operation is the same as for the SH-3.
2. In privileged DSP mode, operation is the same as in privileged mode.
3. In user DSP mode, SR can be read with an STC instruction.
4. In user DSP mode, an LDC instruction can be issued for SR, but in this case DSP-related bits
