Figure 9. Internal Serial Clock, Continuous Operation
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
Figure 9. CS may be permanently tied to ground, simplify-
ing 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 low power 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.
