Chip Select (CS)
CS gates all communication to the device and can be
used to select multiple devices that share the same
SCK and SDO/RDY pins. This pin is also used to
control the internal conversions, which begin on the
falling edge of CS. Raising CS before the first internal
conversion is complete places the device in Single
Conversion mode. Leaving CS low will place the
device in Continuous Conversion mode (i.e., additional
internal conversions will automatically occur). CS may
be tied permanently low for two-wire Continuous
Conversion mode operation. SDO/RDY enters a high-
impedance state with CS high.
