Pin function #1 represents the reset state of the hardware. Pin functions can be changed via the SIM pin, mux-control registers in Freescale or user firmware.
RESETB is an open-drain, bidirectional pin. Reset must be pulled high at startup. After startup, Reset may be asserted to reset the device.
RGPIO3/SDA1/SSB = Low at startup selects SPI. High at startup selects I
