difference between modes of conversion
The major difference between sweep mode (mode 10) and repeat sweep mode (mode 11) is that the sweep
sequence ends after the FIFO is filled up to the programmed threshold. The repeat sweep can either dump the
FIFO (by ignoring the FIFO content but simply reconfiguring the device) or read the FIFO and then repeat the
conversions on the the same sequence of the channel as before.
FIFO reads are expected after the FIFO is filled up to the threshold in each case. Mode 10 – the device allows
only FIFO read or CFR read or CFR write to be executed. Any conversion command is ignored. In the case of
mode 11, in addition to the above commands, conversion commands are also executed , i.e. the FIFO is cleared
and the sweep sequence is restarted.
Both single shot and repeat modes require selection of a channel after the device is configured for these modes.
Single shot mode does not use the FIFO, but repeat mode does. When the device is operating in repeat mode,
the FIFO can be dumped (by ignoring the FIFO content and simply reconfiguring the device) or the FIFO can
be read and then the conversions repeated on the same channel as before. However, the channel has to be
selected first before any conversion can be carried out. The devices can be programmed with the following
sequences for operating in the different modes that use a FIFO:
