Timing and Control
Convert Start Timing—Full Control Mode
R/C must be low before asserting both CE and CS. If it
is high, a brief read operation occurs possibly resulting
in system bus contention. To initiate a conversion, use
either CE or CS. CE is recommended since it is shorter
by one propagation delay than CS and is the faster input
of the two. CE is used to begin the conversion in Figure 4.
The STS output is high during the conversion indicating
the ADC is busy. During this period, additional convert
start commands will be ignored, so that the conversion
cannot be prematurely terminated or restarted. However,
if the state of A0 is changed after the beginning of the
conversion, any additional start conversion transitions
will latch the new state of A0, possibly resulting in an
incorrect conversion length (8 bits vs. 12 bits) for that
conversion.
Read Timing—Full Control Mode
Figure 5 illustrates the read-cycle timing. While reading
data, access time is measured from when CE and R/C
are both high. Access time is extended 10ns if CS is used
to initiate a read.
