PIC24FJ16MC101/102 AND PIC24FJ32MC101/102/104
20.0 COMPARATOR MODULE
Note 1: This data sheet summarizes the features
of the PIC24FJ16MC101/102 and
PIC24FJ32MC101/102/104 families of
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to Section 48. “Comparator
with Blanking” (DS39741) of the
“PIC24F Family Reference Manual”,
which is available from the Microchip
website (www.microchip.com).
2: It is important to note that the
specifications in Section 26.0 “Electri-
cal Characteristics” of this data sheet,
supercede any specifications that may be
provided in PIC24F Family Reference
Manual sections.
3: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
The PIC24FJ16MC101/102 and PIC24FJ32MC101/
102/104 Comparator module provides three
comparators that can be configured in different ways.
As shown in Figure 20-1, individual comparator options
are specified by the Comparator module’s Special
Function Register (SFR) control bits.
These options allow users to:
• Select the edge for trigger and interrupt generation
• Select low-power control
• Configure the comparator voltage reference and
band gap
• Configure output blanking and masking
The comparator operating mode is determined by the
input selections (i.e., whether the input voltage is
compared to a second input voltage, to an internal
voltage reference.
