The dot pattern for the character “A” (ASCII 41H) is:

. . . . 0 . . . . . . .
. . . 0 . 0 . . . . . .
. . 0 . . . 0 . . . . .
. 0 . . . . . 0 . . . .
0 . 0 . 0 . 0 . 0 . . .
0 . . . . . . . 0 . . .
0 . . . . . . . 0 . . .

Next, convert each row of dots into a 16-bit value. Assign logical one (1) to
every position that does not contain a “fired” dot and assign a logical zero (0) to
every position that contains a “fired” dot. Pad the resultant 12-bit value on the
left with four zeros.
