1. How is the LCD placed into the 4-bit data mode?

2. How is the cursor in an LCD positioned to a specific, user-selected location on the display?

3. Given the state of RS, E and R/W~, and the data (in hex) needed to send an 'H' to the LCD for display.

4. What is minimum pulse width for the control signal EN in a ST7036 LCD.

5. Is the chip enables BCS~active-HIGH or active~LOW in this LCD?

6. State briefly the advantage of operating the LCD in each of the following data modes:

i. 8-bit parallel

ii. 4-bit parallel

iii. serial

7. Explain how a keypad interface IC works?

8. Given the bit pattern on Port A is PA7-4 = "1101" and data on PA3-0 = "1101", identify the active key.
