$LCDRS = [&H]address
Remarks
Address The address where must be written to, to enable the LCD display.The db0-db7 lines of the LCD must be connected to the data lines D0-D7. (or is 4 bit mode, connect only D4-D7)On systems with external RAM, it makes more sense to attach the LCD to the data bus. With an address decoder, you can select the LCD display.

(or is 4 bit mode, connect only D4-D7)The RS line of the LCD can be configured with the LCDRS statement.On systems with external RAM, it makes more sense to attach the LCD to the data bus.
