Figure 6. External Serial Clock, 3-Wire Operation (CS = 0)
External Serial Clock, 3-Wire I/O
This timing mode uses a 3-wire serial I/O interface. The
conversionresultisshiftedoutofthedevicebyanexternally
generated serial clock (SCK) signal, see Figure 6. CS is
permanently tied to ground, simplifying the user interface
or isolation barrier.
The external serial clock mode is selected at the end of
the power-on reset (POR) cycle. The POR cycle is typically
concluded 4ms after VCC exceeds 2V. The level applied to
SCK at this time determines if SCK is internally generated
or externally applied. In order to enter the external SCK
mode, SCK must be driven LOW prior to the end of the
POR cycle.
Since CS is tied LOW, the end-of-conversion (EOC) can be
continuously monitored at the SDO pin during the convert
and sleep states. EOC may be used as an interrupt to an
external controller. EOC = 1 while the conversion is in
progress and EOC = 0 once the conversion is complete.
On the falling edge of EOC, the conversion result is load-
ing into an internal static shift register. The output data
can now be shifted out the SDO pin under control of the
externally applied SCK signal. Data is updated on the fall-
ing edge of SCK. The input data is shifted into the device
through the SDI pin on the rising edge of SCK. On the
24th falling edge of SCK, SDO goes HIGH, indicating a
new conversion has begun. This data now serves as EOC
for the next conversion.
