Configuring Analog Port Pins
The use of the ADPCFG and TRIS registers control the
operation of the A/D port pins. The port pins that are
desired as analog inputs must have their correspond-
ing TRIS bit set (input). If the TRIS bit is cleared (out-
put), the digital output level (VOH or VOL) will be
converted.
When reading the PORT register, all pins configured as
analog input channel will read as cleared (a low level).
Pins configured as digital inputs will not convert an ana-
log input. Analog levels on any pin that is defined as a
digital input (including the ANx pins), may cause the
input buffer to consume current that exceeds the
device specifications.
8.2.1
I/O PORT WRITE/READ TIMING
One instruction cycle is required between a port
direction change or port write operation and a read
operation of the same port. Typically this instruction
would be a NOP.

Input Change Notification Module
The Input Change Notification module provides the
dsPIC30F devices the ability to generate interrupt
requests to the processor in response to a change-of-
state on selected input pins. This module is capable of
detecting input change-of-states even in Sleep mode,
when the clocks are disabled. There are up to 22 exter-
nal signals (CN0 through CN21) that may be selected
(enabled) for generating an interrupt request on a
change-of-state.
