The bit allocation for Port 80 is the same as for the POST code.
How to read the 8-Bit POST Code
Due to the fact that only 4 LEDs are available and 8 bits must be displayed, the POST code output is multiplexed on
the General Purpose LEDs.

Under normal operating conditions, the General Purpose LEDs should not remain lit during
boot-up. They are intended to be used only for debugging purposes. In the event that a
General Purpose LED lights up during boot-up and the CP3005-SA does not boot, please
contact Kontron for further assistance.
