7.9.1.
Mainly, the digital connector is meant to expand the programmer for extra needs. Address lines A0-A7
together with the Map Select Lines F8-FF allows the user direct access to an area of 2 K. Example would
be adding a simple addressed I/O register by using the selection lines. If more complexity is needed, a full
FPGA can be mounted on the DB board
Note: All the pins are limited to 5 Volt input\output!!!! However, there are protections, please take
precautions in order to avoid damage of the main board.

Description
Address lines
Data Lines active during Rd or Wr signals
Read : A negative pulse will indicate a sampling of the data on the Data Bus
Write : A Negative pulse will indicate when data is available on the Data Bus
This signal goes low by powering the PTC or by pressing the reset button.
This line can be pulled low by application.
Check firmware documentation for resetting by software.
I2c Bus
Note: These pins are limited to 5 Volt input\output!!!!
The full Port E of the Atmega core is mounted to these pins. This allows us to use
advanced features like PWM, UARTS, Time Measurements, etc….
By using firmware that supports these functions, really nice application specific
requirements can be fulfilled.
Digital Ground
5 Volt Digital Supply. Maximum current to get out of this supply : ….mA
