Port 84 Codes
Moving from left to right, the series of numbers assigned to the first four LEDs is translated
into a code, which consists of any characters 0 through 9 or A through F. The series of
numbers assigned to the next four LEDs is translated into the same code, resulting in a final
two-character code. Refer to Table 5-2 to determine how to read the code from the LED
pattern.
