3.2
3.2.1
The CPU processing modes can be extended using the mode bit (MD) and DSP bit (DSP) in the
status register (SR), as shown below.
Table 3.1
As shown above, the extension of the DSP function by the DSP bit can be specified independently
of the control by the MD bit. Note, however, that the DSP bit can be modified only in privileged
mode. Before the DSP bit is modified, a transition to privileged mode or privileged DSP mode is
necessary.
3.2.2
In DSP mode, a part of the P2 area in the virtual address space can be accessed in user DSP mode.
When this area is accessed in user DSP mode, this area is referred to as a Uxy area. X/Y memory
is then assigned to this Uxy area. Accordingly, X/Y memory can also be accessed in user DSP
mode.
