Multi Digit Blink Code Application defined blink codes.
The Status LED
The programmer can send different single or multi digit blink codes to the status LED by using the application
variable “Blinkcode”. In the application code, the programmer would assign a 1, 2 or 3 digit non-zero value to
the Blinkcode variable (i.e. Blinkcode = 501). The BIOS would then read this value, and then start flashing the
Status LED to the assigned code, for example, in the example above (Blinkcode = 501) the Status LED would
flash 5 times followed by a short pause then flash 10 times followed by a short pause then flash once then stop
if no other code has been assigned. If a new code was assigned during the time that the code was flashing,
there would be a longer pause before the next code began flashing. After the BIOS reads a blink code it will
reset the Blinkcode variable to 0 allowing the application to test and see if the BIOS is ready for the next blink
code assignment.
The following is an example of valid Blink Code assignments:
[0]
No Blink Code Assigned
[1 – 9] Single Digit Blink Code
[10 – 99] Two Digit Blink Code
[100 – 999] Three Digit Blink Code
