8.2
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 (V
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
analog 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
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.

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 external signals (CN0 through CN21) that may
be selected (enabled) for generating an interrupt
request on a change-of-state.
