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.
Table 10: POST Code Sequence
STATE

All LEDs are OFF; start of POST sequence

Low nibble; state 2 is followed by state 0
The following is an example of the General Purpose LEDs' operation if the POST configuration is en-
abled (see also Tables 8 and 9).
