1.6.4.2 SPI communication (connecting to an SPI master)
Figure 8 shows how to connect a u-blox GPS receiver to a host/master. The signal on the pins must meet the
conditions specified in the Data Sheet.

Figure 8: Connecting to SPI Master
For those u-blox 6 modules supporting SPI the SPI MOSI, MISO and SCK pins share a configuration
function at start up. To secure correct receiver operation make sure that the SS_N pin is high at start up.
Afterwards the SPI function will not affect the configuration pins.
