10.1.1
In addition to the PORT, LAT and TRIS registers for
data control, some port pins can also be individually
configured for either digital or open-drain output. This
is controlled by the Open-Drain Control register,
ODCx, associated with each port. Setting any of the
bits configures the corresponding pin to act as an
open-drain output.
TABLE 10-1:
10.2
The AD1PCFGL and TRIS registers control the opera-
tion of the analog-to-digital (A/D) port pins. The port
pins that are to function as analog inputs must have
their corresponding TRIS bit set (input). If the TRIS bit
is cleared (output), the digital output level (V
is converted.
When the PORT register is read, all pins configured as
analog input channels are read as cleared (a low level).
Pins configured as digital inputs do not convert an
analog input. Analog levels on any pin defined as a
digital input (including the ANx pins) can cause the
input buffer to consume current that exceeds the
device specifications.

)
The open-drain feature allows the generation of
outputs higher than V
digital-only pins by using external pull-up resistors.
The maximum open-drain voltage allowed is the same
as the maximum V
Some I/O pins may have internal analog functionality
that will not be shown on the device pin diagram.
These pins must be treated as analog pins. Table 10-1
lists all available pins and their functionality.
10.2.1
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 an NOP, as shown in Example 10-1.
