FUNCTIONAL DESCRIPTION
FUNCTIONAL INTERNAL BLOCK DESCRIPTION
determined by the A/Da[2 : 0] bits in the serial normal input
frame (refer to Table 11 , page 28 ).
Three different types of conversion can occur (refer to
? Single Conversion 00X does a single conversion of
inputs AN0/ANALOGOUT_A or AN1/ANALOGOUT_B.
? Double Conversion 1XX does a double conversion of
channels A and B, A and A , B and B , or
AN2/ANALOGIN_A and AN3/ANALOGIN_B,
respectively.
? Auto-Select Conversion 011 does a single
conversion of one of the outputs from the analog
encoder interface, as selected by the digital outputs of
the analog encoder interface, DENCA and DENCB.

27. DENCA and DENCB values are captured at the output of the 3 or 6 Edge filter on SCLK rising edge, then immediately
shifted out in the MISO data when CE is high.
28. Inputs are listed in order of conversion.
A/D Conversion Flow
There is a START conversion bit in the serial channel. The
presence of this bit begins a conversion cycle on the input(s)
selected in that frame. If the ADC is converting when a
subsequent START bit arrives, this start request will be
shows how this process works. The current conversion
completes during the frame prior to the data being returned.
If there is a START bit in that input frame, another conversion
is begun as the previous conversion’s data is being shifted
out. If there is no START bit in the input frame, then another
conversion is begun the frame following receipt of the start
bit. The single conversion rate is paced at four frames for
configuration bit 3 =0 or eight frames (or less) for
configuration bit 3 =1, including sampling time (refer to
order to simplify implementation of the 34921, the user must
ensure that no A/D conversions are in progress when an
INFO word is requested. For input pairs, the inputs are listed
