ADS7863
SBAS383–JUNE 2007
The CONVST and RD pins can still be tied together,
but do not need to be issued every 16 CLOCK
cycles. Output data are presented on both terminals,
SDOA and SDOB.
For Mode II, a special read mode is available in the
ADS7863 where both data results can be read out,
triggered by a single RD pulse. To activate this
mode, bit S4 in the SDI Register must be set to '1'
(see also the
Serial Data Input
section).
The special read mode is not available in Mode I or
Mode III.
Figure 20
illustrates the special read mode.
