In both modes, Pin control Mode and SPI mode control, the SPI can be used to read back the data generated by the Σ-Δs.
In SPI control mode, the SPI reads back the Σ-Δ conversion data by setting the GENERAL_USERS’s bits 3 and 4 as described Table 23.
In both cases the maximum ODR can be calculated with the following equation.
ODR = Output data rate
SCLK = SPI clock in SPI Control Mode
Nchannel= number of channels which is always 8
