Set Brightness
Load Four Characters
Load an “S” in the left hand digit.
Load a “T” in the next digit.
Load an “O” in the next digit.
Load a “P” in the right hand digit.
If you loaded the information correctly, the display
now should show the word “STOP.”
Blink a Single Character
Into the digit, second from the right, load the hex
code “CF,” which is the code for an “O” with the
D7 bit added as a control bit.
Note:
Load enable blinking character into the control
word register. The display should show “STOP”
with a flashing “O”.
Set the brightness level of the entire display to
your preference (example: 100%)
The “O” is the only digit which has the control bit
(D7) added to normal ASCII data.
