AD777x: What is the maximum ODR when using SPI for ΣΔ read back?

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.   

ODR = Output data rate
SCLK = SPI clock in SPI Control Mode
Nchannel= number of channels which is always 8
