The GPIO mux registers must be configured to connect this peripheral to the device pins. To avoid glitches on the pins, the GPyGMUX bits must be configured first (while keeping the corresponding GPyMUX bits at the default of zero), followed by writing the GPyMUX register to the desired value.
For proper SDFM operation, use the following GPIO input qualification. Other GPIO qualifications are not supported.
See the General-Purpose Input/Output (GPIO) chapter for more details on GPIO mux and settings.
