a.
Data Register (DR): Dris a register used for temporary Storage of the data read/write form/into DD
RAM and CG RAM.
b.
Instruction Register (IR): is a register available for storing the instruction codes and address
information 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 can
not accept the next instruction.
d.
Character Generator (CG) ROM: This ROM Generates character pattern from 8-bit character code
and provides 192 character patterns.
e.
Character Generator (CG)RAM: This RAM allows the user to rewrite the character patterns freely
according to the program.
f.
Address Counter (AC): This address counter is used to give the address information of DD RAM
and CG RAM.
g.
Display Data (DD) RAM: This display data RAM is used to store the display data expressed by 8-bit
character code . The capacity is 80x 8bits and data for 80 characters can be storage.
h.
