Figure 4: Expansion Connector Pinout
Each pin, except GND and NC, is controlled through individual analog switch. GreenPAK Designer
can enable or disable external pins, as it is shown on
Figure 5 . There is no individual control of each
key: when one key is turned on, all others are also turned on.
Figure 5: Expansion Connector Control in GreenPAK Designer
The Expansion Connector is enabled only in Emulation mode or Test mode. To enter either of these
two modes, the target GreenPAK device must be inside the socket the DIP Adapter Connector. When
the Test mode button is pressed, the software will first read the chip to verify if it was inserted correctly,
and then configure the GreenPAK DIP Development Board as it was set in Emulation mode. After the
Emulation button is pressed, the software will automatically perform the following steps:
▪
Check chip presence;
▪
Open all expansion port switches (allowing external signals/loads to be left connected to Expansion
Connector);
▪
Load target configuration into the target GreenPAK device using internal power;
▪
Configure Development Board as it was selected in Emulation Tool window.
Note that the GreenPAK device has internal OTP memory which is normally loaded into RAM registers
at initialization time. “Emulation mode” will bypass this load and write the updated version of the project
directly into the RAM register inside the GreenPAK chip many times, but after power loss all internal
data will be lost. Also, when the GreenPAK chip is already programmed - user can use Emulation mode
