data input—address/command bits
The four MSBs (D7–D4) of the input data register are the address or command. These can be used to address
one of the 11 input channels, address one of three reference-test voltages, or activate software power-down
mode. All address/command bits affect the current conversion, which is the conversion that immediately follows
the current I/O cycle. They also have access to CFGR1 except for command 1111b, which is reserved.
data output length
CFGR1 bits (D3 and D2) of the data register select the output data length. The data-length selection is valid
for the current I/O cycle (the cycle in which the data is read). The data-length selection, being valid for the current
I/O cycle, allows device start-up without losing I/O synchronization. A data length of 8, 12, or 16 bits can be
selected. Since the converter has 12-bit resolution, a data length of 12 bits is suggested.
With D3 and D2 set to 00 or 10, the device is in the 12-bit data-length mode and the result of the current
conversion is output as a 12-bit serial data stream during the next I/O cycle. The current I/O cycle must be exactly
12 bits long for proper synchronization, even when this means corrupting the output data from a previous
conversion. The current conversion is started immediately after the twelfth falling edge of the current I/O cycle.
With bits D3 and D2 set to 11, the 16-bit data-length mode is selected, which allows convenient communication
with 16-bit serial interfaces. In the 16-bit mode, the result of the current conversion is output as a 16-bit serial
data stream during the next I/O cycle with the four LSBs always reset to 0 (pad bits). The current I/O cycle must
be exactly 16 bits long to maintain synchronization even when this means corrupting the output data from the
previous conversion. The current conversion is started immediately after the sixteenth falling edge of the current
I/O cycle.
