PIC24FJ64GB004 FAMILY
10.1.1
In addition to the PORT, LAT and TRIS registers for
data control, each port pin 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 con-
figures the corresponding pin to act as an open-drain
output.
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
10.2
The AD1PCFGL and TRIS registers control the opera-
tion of the A/D port pins. Setting a port pin as an analog
input also requires that the corresponding TRIS bit be
set. If the TRIS bit is cleared (output), the digital output
level (V
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.
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 a NOP (Example 10-1).

10.2.2
The voltage tolerance of pins used as device inputs is
dependent on the pin’s input function. Pins that are
used as digital only inputs are able to handle DC
voltages up to 5.5V, a level typical for digital logic
circuits. In contrast, pins that also have analog input
functions of any kind can only tolerate voltages up to
