The First Black Data Location

Gives the half word count that black data first appeared in output of

the BRC. If the first half word contains black data the register will

remain at 000H. If the second half word contains data the register will

contain 0001H Etc. If black data in not present in the entire line (all

white line), register will be equal to the line length.

First Half Word Location = Register Value + 1.
