2.7.3 Dead reckoning interface
MG260 module provides a full-digital interface for dead reckoning function: SPI
bus (GPS_SCK, GPS_MOSI and GPS MISO) with 2 different chip select
(GPS_PCS0_N and GPS_PCS1_N), and 1 GPI (GPS_EXTINT0).
The SPI bus is used to drive an ADC for temperature monitoring (GPS_PCS0_N) and for
gyroscope (GPS_PCS1_N).
The distance information is given by the odometer and optionally by the reverse
indicator.
