Please refer to the '
DIABLO16-4DGL-Internal-
Functions.pdf ' document for information on how to
set the DIABLO16 pin mappings.
As per the table, not all GPIO can be configured to be
every serial port, or RX/TX.
Serial ports output at the level of TTL 3.3V, however
are 5V tolerant, so can accept communications from
5V devices.
4.2. General Purpose I/O
There are 16 general purpose Input/Output (GPIO)
pins available to the user. These provide flexibility of
individual bit operations along with serving
collectively for byte wise operations using the BUS
functions

PA0-PA3:
General purpose I/O pins, or can serve as Analog Input
pins. Each pin can be individually set for INPUT or
OUTPUT or ANALOG. Power-Up Reset default is all
INPUTS. Digital GPIO can source/sink 10mA. For more
information, the Specifications section.
These pins have a 0 to 3.3V range, and have 12 bit
resolution.
For more information, see
Section 4.11 ‘Analog
Inputs’.
PA4-PA11:
General purpose I/O pins. Each pin can be individually
set for INPUT or OUTPUT. Power-Up Reset default is
all INPUTS. When set as Digital Inputs, the pins are 5V
tolerant. Digital GPIO can source/sink 10mA. For more
information, see the Specifications Section.
