The configuration guidelines give the required setup
values for the conversion speeds above 500 ksps,
since they require external V
are some differences in the configuration procedure.
Configuration details that are not critical to the
conversion speed have been omitted.

conversion rates above 500 ksps.
FIGURE 20-2:
20.7.1
The configuration for 1 Msps operation is dependent on
whether a single input pin is to be sampled or whether
multiple pins are to be sampled.
20.7.1.1
For conversions at 1 Msps for a single analog input, at
least two sample and hold channels must be enabled.
The analog input multiplexer must be configured so
that the same input pin is connected to both sample
and hold channels. The A/D converts the value held on
one S&H channel while the second S&H channel
acquires a new input sample.

The ADC can also be used to sample multiple analog
inputs using multiple sample and hold channels. In this
case, the total 1 Msps conversion rate is divided among
the different input signals. For example, four inputs can
be sampled at a rate of 250 ksps for each signal, or two
inputs could be sampled at a rate of 500 ksps for each
signal. Sequential sampling must be used in this
configuration to allow adequate sampling time on each
input.
