to set the DIABLO16 pin mappings.
General Purpose I/O
4.2.
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

information.
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. When set as Digital Inputs,
the pins are 5V tolerant. Digital GPIO can
source/sink 10mA. For more information see
Chapter 17, ‘Specifications and Ratings’.
When set as Analog Inputs, the 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
Section 14, ‘Specifications and Ratings’.
PA12-PA13:
PA12 and PA13 are reserved and are used
exclusively for the resistive touch controller. These
pins are NOT to be connected, else Touch may not
perform correctly. These feature 4.7K pull up
resistors on PA12 and PA13. These are present on
the Headers for special cases only where Touch is
not installed. Do not attempt to use these pins in
normal situations.
PA14-PA15:
Input only pins. These pins can only be Digital
Inputs.
Note: All GPIO pins are 5.0V tolerant.
