How to display my date in the 2nd line of the LCD?

Question

Below are the codes I using to display dates and times and basically I used the function "write(hr1,hr0,min1,min0,sec1,sec0);" to display the time and "day_compute(day);" to display what the day for the input date. For simplicity, I just show the input send to LCD between these 2 functions. I want the time to display on the 1st line of the screen and day to display on the 2nd line of the screen, what command line should I add in between this 2 so it will separate the day to the 2nd line?Refered to the datasheet but still not able to understand how to do that.

     void LCD_set();

     void main()
    {                   
           TRISA=0x00;
           TRISD=0x00
        
     while(1)
    {                       
                initialize();               
                write(hr1,hr0,min1,min0,sec1,sec0);
                day_compute(day);           
    }

        
     void initialize()
    {        
          PORTD=0x00;
          LCD_set();
          PORTD=0x0C;
          LCD_set();
          PORTD=0x06;
          LCD_set();
          PORTD=0x80;
          LCD_set();   
    }
     

Answer 1

Using these commands sets the configuration and positions the cursor.

 Rs    Cmd  Executes
 18     38  2 lines and 5×7 matrix
 16     80  Force cursor to beginning ( 1st line)
 17     C0  Force cursor to beginning ( 2nd line)

Answer 2

Based on the explanation given by Tony, I understood the command line and found my mistake already. My mistake is in the void initialize() command

originally I using void initialize()

 {

  PORTD=0x00;
  LCD_set();
  PORTD=0x0C;
  LCD_set();
  PORTD=0x06;
  LCD_set();
  PORTD=0x80;
  LCD_set();

  }

where 0x00 and 0x06 is not needed and after added in PORTD=0x38 to declare it as 2 lines and 5x7 matrix as the code below,

 void initialize()
{


PORTD=0x0C;
LCD_set();
PORTD=0x38;
LCD_set();
PORTD=0x80;
LCD_set();

}

and write PORTD=0xC0 in between the print time and date function i obtained my desired result.

        write(hr1,hr0,min1,min0,sec1,sec0);
        PORTD=0xC0;
        LCD_set();
        write1(date02,date01,month02,month01,year3,year2,year1,year0);
