start of active data; see Table 50
sliced data identification: NEP

, SDID5 to SDID0, freely programmable via I

C-bus subaddress 5EH, bits 5 to 0, e. g. to be used as

Dword count: NEP

, DC5 to DC0. DC describes the number of succeeding 32-bit words:
For SAV/EAV mode DC is fixed to 11 Dwords (byte value 4BH)
For ANC mode it is: DC =
1
4
(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.
Note that the number of valid bytes inside the stream can be seen in the BC byte.
