The System Control Interface (SCIF) controls the Oscillators, PLL, Generic Clocks, BODs, the
voltage regulators and general purpose low power registers.
Table 8-1.
The SCIF provides a number of generic clock outputs, which can be connected to output pins,
multiplexed with GPIO lines. The programmer must first program the GPIO controller to assign
these pins to their peripheral function. If the I/O pins of the SCIF are not used by the application,
they can be used for other purposes by the GPIO controller. Oscillators pins are also multiplexed
with GPIO. When oscillators are used, the related pins are controlled directly by the SCIF, over-
riding GPIO settings.
