PIC32MX3XX/4XX
12.2.9
Certain PIC32MX3XX/4XX I/O port pins provide Input
Change notification that can generate interrupt
requests to the processor in response to a Change-Of-
State (COS) on those selected input pins. The initial
state of any enabled Change Notice (CN) pin must be
established by reading the corresponding PORT regis-
ter. This feature is capable of detecting input COS even
in Sleep mode, when the clocks are disabled. Depend-
ing on the device pin count, there are up to 22 external
signals (CN0 through CN21) that may be selected
(enabled) for generating an interrupt request on a COS.
The following control registers are associated with the
change notice module:
• CNCON
• CNEN
• CNPUE
The CNCON control register ON bit enables or disables
the CN module and its ability to generate interrupts or
respond to mismatch conditions.
The CNEN (change notice enable) register control bits
enable each CN input. Setting any of these bits enables
a CN for the corresponding pins.
The CNPUE (change notice pull-up enable) register
control bits enable a weak pull-up to a corresponding
CN input pin. The pull-ups act as a current source that
is connected to the pin, and eliminate the need for
external resistors when push button or keypad devices
are connected.
DS61143C - page 320
Note:
INPUT CHANGE NOTIFICATION
Pull-up resistors on change notification
pins should always be disabled whenever
the port pin is configured as a digital
output.
Preliminary
TABLE 12-11: CHANGE NOTICE PIN AND
12.2.10
The Change Notice module is enabled as a source of
interrupts via the respective CN interrupt enable bits:
• CNIE (IEC1<0>)
• CNIF (IFS1<0>)
The interrupt priority level bits and interrupt subpriority
level bits must also be configured:
• CNIP<2:0> (IPC6<20:18>)
• CNIS<1:0> (IPC6<17:16>)
To enable CN interrupts, the ON bit (CNCON<15>)
must = 1, one or more CN input pins must be enabled
and the Change Notice Interrupt Enable bit, CNIE,
must = 1.
