PI_ENABLE
2ADC Calibration Word <32:0>
three registers (13, 14 and 15). These registers all have their
default value and changing this value is not recommended.
The default register values are:

The calibration word for the ADCs is distributed over
calib_adc<11:0>: 101011011111
calib_adc<23:12>: 011011011011
calib_adc<32:24>: 000011011011
The timing of the SPI register is explained in the timing
SPI_IN (15:12): Address bits
SPI_IN (11:0): Data bits
When SPI_ENABLE is asserted the parallel data is loaded

Data Interface (SPI)
Interface) uses a serial input to shift the data in the register
buffer. When the complete data word is shifted into the
register buffer the data word is loaded into the internal
register where it is decoded.
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.
