External Reference Signal
Internal Reference Signal
When external voltage references are used, the comparator module can be configured to have
the comparators operate from the same or different reference sources. The reference signal must
be between V
The comparator module also allows the selection of an internally generated voltage reference for
the comparators. The
Reference Module that provides this signal. The internal reference signal is used when the com-
parators are in mode CM2:CM0 = 010
is applied to the V
The internal voltage reference may be used in any comparator mode. When used in this fashion
the I/O/V
REF
pin may be used for I/O. The voltage reference is connected to the V
SS
and V
