The first 11 application modes are given in this section. Schematic diagrams of these application modes are given in
Table 11. In this table the basic features are mentioned and also the extra features in case of microcontroller mode are
given. It should be noted that the blocks running at the crystal clock (XTAL) are marked unshaded while the blocks
running at the PLL clock are shaded.
