Reading the Display:
Convert the hexadecimal display into binary display.
If more than two causes, they will be added.
Example
When 42 is displayed:
Higher bit : 4 = 0100 t b6
Lower bit : 2 = 0010 t b1
In this case, the retry cause is combined of "CLV unlock"
and "ader5".
When A2 is displayed:
Higher bit : A = 1010 t b7+b5
Lower bit : 2 = 0010 t b2
The retry cause in this case is combined of "access fault",
"IVR rec error", and "ader5".
