Note:
*: The segment register for LCD is allocated in the address range from 100H to 1FFH.
The user can freely set the segment register's address and bit that correspond to each segment pin. Even
when L32 to L35, which have a port option, are used as output ports, it is possible to freely set their
corresponding address and bit.
