RS pin is used to select the register in the LCD ie,
when RS = 0 , used to send command to the LCD (JHD162A) controller from the P89v51RD2 (command means shift the courser ,blink etc)
When RS = 1 ,used to send Data to the LCD controller (JHD162A) from the P89v51RD2 for displaying on LCD.
RW is used to write or read the information from /to LCD controller
RW should zero when send command /data to LCD
RW one when read some information from LCD (eg: Reading Busy flag)

every command or data send to the LCD we need give a high to low signal to the E
