Serial Data Output
The serial data output sequence is MSB (DB11) first to LSB
(DB0) last. The MSB (DB11) data bit appears at SDO when STS
goes low. The second most significant bit appears at SDO on
the SDC high-to-low transition next. The LSB (DB0) is present
at SDO on the 11th SDC high-to-low transition.
Further information regarding serial control and timing is
shown in Figure 6., Table 4.and Table 5.
For a minimum interconnect serial environment, the channel
address state can be generated in at least two ways, using an
address counter, or using an address serial to parallel converter.
WR can then be used as the counter clock or shift register load
signal as well as the A/D converter start convert signal on the ris-
ing edge. (Note that the falling edge loads the address present at
the address port.)
