Internal Serial Clock, 3-Wire I/O, Continuous
Conversion
This timing mode uses a 3-wire, all output (SCK and SDO)
interface. The conversion result is shifted out of the device
by an internally generated serial clock (SCK) signal, see
Figure9.CSmaybepermanentlytiedtoground,simplifying
the user interface or isolation barrier. The internal serial
clock mode is selected by tying EXT HIGH.
During the conversion, the SCK and the serial data output
pin (SDO) are HIGH (EOC = 1) and BUSY = 1. Once the
conversion is complete, SCK, BUSY and SDO go LOW
(EOC = 0) indicating the conversion has finished and the
device has entered the sleep state. The part remains in
the sleep state a minimum amount of time (≈500ns) then
immediately begins outputting data. The data output cycle
begins on the first rising edge of SCK and ends after the
32nd rising edge. Data is shifted out the SDO pin on each
falling edge of SCK. The internally generated serial clock
is output to the SCK pin. This signal may be used to shift
the conversion result into external circuitry. EOC can be
latched on the first rising edge of SCK and the last bit of
the conversion result can be latched on the 32nd rising
edge of SCK. After the 32nd rising edge, SDO goes HIGH
(EOC = 1) indicating a new conversion is in progress. SCK
remains HIGH during the conversion.
