convert Ascii value to Binary or text
First, split FFF7BBFF into four bytes: FF-F7-BB-FF

Each byte corresponds to a column in your table. If it was written like any normal documentation I would say "the first byte" is on the right. However, taking into account unconventional presentation, all bets are off. In fact, it looks like they number bytes left-to-right (see below).

Second, convert hexadecimal presentation into binary, for example your "BB" becomes "10111011". I won't be explaining how to do it here, this is not the right place for basic things children learn in school.

Third, compare each bit to corresponding byte column, with right-most bit (hopefully) being bit #0 (top row). For example, if you compare "10111011" to "the third byte" column you would see that two states are "effective" i.e. equal to zero: #2 (ACC Off) and #6 (Custom alarm).

The fact that bit #3 of this column is supposed to be 1 all the time ("reserves"?!) and bit 3 of F7 is not, tells me they indeed number bytes left-to-right.
