FIGURE 11. Reading Data in Cycling Mode.
FIGURE 12. Reading Data in Cycling Mode.
With (A2 A1 A0) = 110 the interface is running in a cycle
mode (see Figures 11 and 12). Here, data from channel A0
is read on the first RD signal, then A1 on the second,
followed by B0, B1, C0 and finally C1 before reading A0
again. Data from channel A0 is brought to the output first
after a reset-signal or after powering the part up.
The third mode is a FIFO mode that is addressed with (A2
A1 A0 = 111). Data of the channel that is converted first will
be read first. So, if a particular channel is most interesting
and is converted more frequently (e.g., to get a history of a
particular channel) then there are 3 output registers per
channel available to store data.
If a read process is just going on (RD signal low) and new
data has to be stored, then the ADS7864 will wait until the
read process is finished (RD signal going high) before the
new data gets latched into its output register.
