Sarada,
You are probably mistaking the BCC and the BSIC.
BSIC = 1 => NCC = 0, BCC = 1
…
BSIC = 7 => NCC = 0, BCC = 7
BSIC = 8 => NCC = 1, BCC = 0
BSIC = 9 => NCC = 1, BCC = 1
As said before, you can’t exceed 7, because it is coded in one byte.
If this operator found a way to code 9 values within one Byte, then they are the next Einsteins.
