For SAV/EAV mode DC is fixed to 11 double words (byte value 4Bh)
For ANC mode it is: DC =

(C + n), where C = 2 (the two data identification bytes IDI1 and IDI2) and n = number of decoded bytes according to
the chosen text standard
It should be noted that the number of valid bytes inside the stream can be seen in the BC byte.
