The sbit type defines a bit within a special function register (SFR). It is used in one of the following ways:
sbit name = sfr-name ^ bit-position;
sbit name = sfr-address ^ bit-position;
sbit name = sbit-address;
sbit LED2=P3^3; //……meanspin 3 of port 3 is named as LED2 (USED IN PROGRAM LATER)
sbit EN=P3^7; //…….meanspin 7 of port 3 is named as EN (USED IN PROGRAM LATER)
sbit RW=P3^6; //……………….
sbit RS=P3^5; //……………….
