A block diagram of the 10-bit ADC is illustrated in

designated AN0-AN15. In addition, there are two ana-
log input pins for external voltage reference connec-
tions. These voltage reference inputs may be shared
with other analog input pins and may be common to
other analog module references.
The analog inputs are connected through two multi-
plexers (MUXs) to one SHA. The analog input MUXs
can be switched between two sets of analog inputs
between conversions. Unipolar differential conversions
are possible on all
the reference, using a reference input pin (see
Figure
The Analog Input Scan mode sequentially converts
user-specified channels. A control register specifies
which analog input channels will be included in the
scanning sequence.
The 10-bit ADC is connected to a 16-word result buffer.
Each 10-bit result is converted to one of eight, 32-bit
output formats when it is read from the result buffer.
