NOTES:
1. H = LOGIC HIGH; L = LOGIC LOW. WITH THE ENABLE INPUT AT
LOGIC HIGH, CHANGES IN BCD INPUT LOGIC LEVELS HAVE NO
EFFECT UPON DISPLAY MEMORY, DISPLAYED CHARACTER, OR DP.
2. THE DECIMAL POINT INPUT, DP, PERTAINS ONLY TO THE
NUMERIC DISPLAYS.
3. THE BLANKING CONTROL INPUT, B, PERTAINS ONLY TO THE
HEXADECIMAL DISPLAYS. BLANKING INPUT HAS NO EFFECT
UPON DISPLAY MEMORY.
