External Serial Clock, Single Cycle Operation
(SPI/MICROWIRE Compatible)
This timing mode uses an external serial clock to shift out
the conversion result and a CS signal to monitor and
control the state of the conversion cycle, see Figure 4.
The serial clock mode is selected by the EXT pin. To select
the external serial clock mode, EXT must be tied low.
The serial data output pin (SDO) is Hi-Z as long as CS is
HIGH. At any time during the conversion cycle, CS may be
pulled LOW in order to monitor the state of the converter.
While CS is pulled LOW, EOC is output to the SDO pin.
EOC = 1 (BUSY = 1) while a conversion is in progress and
EOC = 0 (BUSY = 0) if the device is in the sleep state.
Independent of CS, the device automatically enters the low
power sleep state once the conversion is complete.
When the device is in the sleep state (EOC = 0), its
conversion result is held in an internal static shift regis-
ter. The device remains in the sleep state until the first
rising edge of SCK is seen. Data is shifted out the SDO pin
on each falling edge of SCK. This enables external circuitry
to latch the output on the rising edge of SCK. 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. On the 32nd falling edge of SCK, the device
begins a new conversion. SDO goes HIGH (EOC = 1) and
BUSY goes HIGH indicating a conversion is in progress.
At the conclusion of the data cycle, CS may remain LOW
and EOC monitored as an end-of-conversion interrupt.
Alternatively, CS may be driven HIGH setting SDO to Hi-Z
and BUSY monitored for the completion of a conversion.
