ADS7863
SBAS383–JUNE 2007
As with Special Mode II, these two pins do not need
to be issued every 16 CLOCK cycles. Data are
available on the SDOA pin.
Analogous to Special Mode II, the ADS7863 also
offers a special read mode for Mode IV in which both
data results of a conversion can be read, triggered
by a single RD pulse. In this case as well, bit S4 in
the SDI Register must be set to '1' while the
CONVST and RD pins can still be tied together .
This special read mode (shown in
Figure 21
) is not
available in Mode I or Mode III.
