8. REGISTER FILE (RF)
8.1 Outline of Register File
Figure 8-1 illustrates the register file.
As shown in the figure, the register file consists of control registers existing on a space different from that
of the data memory, and a portion overlapping the data memory.
The control registers set the conditions of the peripheral hardware units.
Data is read from or written to the register file via the window register.
