Oscillator
All conversions and calibrations are timed from a master clock which must be externally
supplied.
A falling transition on this pin sets the CS5126 to the hold state and initiates a conversion. This
input must remain low at least one master clock cycle plus 50ns.
Status at the end of a conversion cycle determines which analog input channel will be acquired
for the next conversion cycle.
When brought low causes the CS5126 to enter a low-power quiescent state. All calibration
coefficients are retained in memory, so no recalibration is needed after returning to the normal
operating mode.
Determines whether data appears in 2’s complement or offset-binary format. If high, 2’s
complement; if low, offset-binary.
Serial data changes status on a falling edge of this input, and is valid on a rising edge.
