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
corresponding TRIS bit set (input). If the TRIS bit is
cleared (output), the digital output level (V
will be converted.
When reading the PORT register, all pins configured as
analog input channels 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.

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.
