24.2.1
The Comparator module has a flexible input and output
configuration to allow the module to be tailored to the
needs of the application. The PIC32MX3XX/4XX com-
parator module has individual control over the enables,
output inversion, output on I/O pin and input selections.
The V
input pin or the CV
tor can select from one of 3 input pins or the IV
addition, the module has two individual comparator
event generation control bits. These control bits can be
used for detecting when the output of an individual
comparator changes to a desired state or changes
states.
If the Comparator mode is changed, the comparator
output level may not be valid for the specified mode
change delay (refer to the device data sheet for more
information).
A single comparator is shown in the upper portion of
Figure 24-2. The lower portion represents the relation-
ship between the analog input levels and the digital out-
put. When the analog input at V
analog input at V
digital low level. When the analog input at V
greater than the analog input V
comparator is a digital high level. The shaded areas of
the output of the comparator in the lower portion of
Figure 24-2 demonstrate the uncertainty that is due to
input offsets and the response time of the comparator.

COMPARATOR CONFIGURATION
Comparator interrupts should be disabled
during a Comparator mode change;
otherwise, a false interrupt may be gener-
ated.

Depending on the Comparator Operating mode, the
inputs to the comparators may be from two input pins
or a combination of an input pin and one of two internal
voltage references. The analog signal present at V
compared to the signal at V
the comparator is set or cleared according to the result
of the comparison (see Figure 24-2).

An external voltage reference may be used with the
comparator by using the output of the reference as an
input to the comparator. Refer to the device data sheet
for input voltage limits.
24.3.0.2
The CV
inputs to the comparator (see Figure 24-1). The CV
provides a user-selectable voltage for use as a compar-
ator reference. Refer to 25.0 “Comparator Refer-
ence” of this manual for more information on this
module. The IV
not change with the device supply voltage. Refer to the
device data sheet for specific details and accuracy of
this reference.
