SFRs consist of five parts. The SFRs, whose address are 0x7E00_F0XX, controls PLL and the clock generators.
They control the output frequency of three PLL's, clock source selection, and clock divider ratio. The SFR's,
whose address is 0x7E00_F1XX, control the bus system, the memory system, and software resets. The SFRs,
whose address is 0x7E00_F8XX, control the power management block. The SFRs, whose address is
0x7E00_F9XX, show the internal status. The information registers, whose address is 0x7E00_FA0X, save user
information until the hardware reset signal (XnRESET) is asserted.
