The System Control Interface (SCIF) controls the oscillators, Generic Clocks, BODs, VREG,
Temperature Sensor, and Backup Registers.
Table 13-1.
In order to use this module, other parts of the system must be configured correctly, as described
below.
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. Oscillator pins are also multiplexed
