10.Display Address

Relations between DD RAM addresses and positions on the LCD are shown below.The DD RAM address (ADD)is set in the address counter (AC) and is represented in hexadecimal.

11.Block Diagram

a. Data Resistor ( DR ) : DR is a register used for temporary storage of the date read/write from/into DDRAM and CG RAM.

b. Instruction Register ( IR ) : IR is a register available for storing the instruction codes and addressinformation of display data ( DD ) RAM and character generator ( CG ) RAM.

c. BUSY FLAG ( BF ) : When the BUSY FLAG is "1", it shows that LCM is in internal operation and it cannot accept the next instruction.

d. Character Generator ( CG ) ROM : This ROM generates character pattern from 8 -bit character codeand provides 192 character patterns.

e. Character Generator ( CG ) RAM : This RAM allows the user to rewrite the character patterns freelyaccording to the program.

f. Address Counter ( AC ) : This address counter is used to give the address information of DD RAM andCG RAM.

g. Display Data ( DD ) RAM : This display data RAM is used to store the display data expressed by 8 - bitcharacter code. The capacity is 80×8 bits and data for 80 characters can be storage.

h. Cursor and Blink Control Circuit : This circuit generates the cursor and blink.
