CONVERTER DATA REGISTER
a. 16-bit Read-Only Register at relative address 0C (HEX). Data in this
register is 12 bits, right-justified. D12 through D15 are always "0" in
the binary data mode and are sign extensions in the two's
complement data mode.
The START SETTLING and EN START CONV controls are essentially
strobes and are effective only at the moment of writing to the Control Register.
Although supplied as two separate control bits for flexibility, these controls usually
are written to the register simultaneously along with the operational mode and
channel selections.
Figures 4.6.2-1 and 4.6.2-2 illustrate a measurement sequence which
uses the basic conversion control method. The sequence is simplified by the fact
that only the NEW DATA RDY flag must be monitored in order to determine when
each conversion has been completed.
The interleaved (pipelined) control method is presented in
Figures 4.6.2-3 and 4.6.2-4. A higher throughput is achieved by using a somewhat
more complex control sequence. With this method, both the SETTLING BUSY and
NEW DATA RDY flags are monitored.
