lcd_symbol( )
Syntax:
lcd_symbol ( symbol, bX_addr );
Parameters: symbol is a 8 bit or 16 bit constant.
bX_addr is a bit address representing the segment location to be used for bit X of
the specified symbol.
1-16 segments could be specified.

This function loads the bits for the symbol into the segment data registers for the
LCD with each bit address specified. If bit X in symbol is set, the segment at
bX_addr is set, otherwise it is cleared. The bX_addr is a bit address into the LCD
RAM.
