When the advanced sequencer, two-cycle command mode or sin-

gle-cycle command mode is enabled, the sequence of analog

input channels is more flexible, and the channel sequence can be

designed to implement multiple effective sample rates. This design

option is useful in applications with a combination of channels with

low frequency or dc signals and channels with high frequency or

ac signals. The Implementing Two Effective Channel Sample Rates

section describes how to design a channel sequence that achieves

two effective sample rates for two sets of channels.

Table 29 and Figure 126 shows an example of a sequence that

achieves three effective sample rates with four analog inputs. The

sequence in Table 29 and Figure 126 can be implemented with

the advanced sequencer and two-cycle command mode, or single-

cycle command mode.

The advanced sequencer, two-cycle command mode, and single-

cycle command mode can also be utilized to perform aperiodic

conversions on analog inputs, for example, when all channels have

dc type signals, or when the channel sequencing involves adaptive

control logic.
