External Serial Clock, 3-Wire I/O
This timing mode utilizes a 3-wire serial I/O interface. The
conversion result is shifted out of the device by an exter-
nally generated serial clock (SCK) signal, see Figure 6. CS
may be permanently tied to ground, simplifying the user
interface or isolation barrier. The external serial clock
mode is selected by tying EXT LOW.
Since CS is tied LOW, the end-of-conversion (EOC) can be
continuously monitored at the SDO pin during the convert
and sleep states. Conversely, BUSY (Pin 2) may be used
to monitor the status of the conversion cycle. EOC or BUSY
may be used as an interrupt to an external controller
Figure 6. External Serial Clock, CS = 0 Operation (3-Wire)
indicating the conversion result is ready. EOC = 1
(BUSY = 1) while the conversion is in progress and
EOC = 0 (BUSY = 0) once the conversion enters the low
power sleep state. On the falling edge of EOC/BUSY, the
conversion result is loaded into an internal static shift
register. The device remains in the sleep state until the
first rising edge of SCK. Data is shifted out the SDO pin
on each falling edge of SCK enabling external circuitry to
latch data on the rising edge of SCK. EOC can be latched
on the first rising edge of SCK. On the 32nd falling edge
of SCK, SDO and BUSY go HIGH (EOC = 1) indicating a
new conversion has begun.
