The timing of the SPI register is explained in the timing diagram below
SPI_IN (15:12): Address bits
SPI_IN (11:0): Data bits
When SPI_ENABLE is asserted the parallel data is loaded into
the internal registers of the LUPA300. The frequency of

Data bits--------------------------------------------------------------------------------
SPI_CLK is 20 MHz or lower. The SPI bits have a default value
that allows the sensor to be read out at full resolution without
uploading the SPI bits.
