NOTE: For most padsMode 0 is the primary mode. When mode 0 is set, the reset value for function mapped to the MUXMODE field is 0b111. The exceptions are pads to be used at boot time to transfer data from selected peripherals pin corresponds to the external flash memoryname of the pin.

Mode 1 to mode 6 are possible modes for alternate functions. On each pin, some modes are used effectively for alternate functions, while other modes are unused and correspond to no functional configuration. The safe mode (default mode 7) avoids any risk of electrical contention by configuring the pin as an input with no functional interface mapped to it. The safe mode is used mainly as the default mode for all pins containing no mandatory interface at the release of power-on reset.  NOTE: For most pads, the reset value for the MUXMODE field is 0b111. The exceptions are pads to be used at boot time to transfer data from selected peripherals to the external flash memory.<br> '''(more information)'''
