SEQUENCER OPERATION
The AD7323 can be configured to automatically cycle through
a number of selected channels using the on-chip sequence
register with the Seq1 bit and the Seq2 bit in the control register.
Figure 44 shows how to program the AD7323 register to
operate in sequence mode.
After power-up, all of the three on-chip registers contain default
values. Each analog input has a default input range of ±10 V. If
different analog input ranges are required, a write to the range
register is required. This is shown in the first serial transfer of
This initial serial transfer is only necessary if input ranges other
than the default ranges are required. After the analog input
ranges are configured, a write to the sequence register is
necessary to select the channels to be included in the sequence.
When the channels for the sequence have been selected, the
sequence can be initiated by writing to the control register and
setting Seq1 = 0 and Seq2 = 1. The AD7323 continues to
convert the selected sequence without interruption provided
that the sequence register remains unchanged, and Seq1 = 0 and
Seq2 = 1 in the control register.
