I found the correct address after a long search on the net.
dr pepper is correct, the 3rd line continues from 1st line and 4th continues from the 2nd.
The start address is as follows:
Line 1: 0x80
Line 2: 0xc0
line 3: 0x94
Line 4: 0xD4
In case there's any confusion, the addresses are 00h, 40h, 14h, 54h, however, commands have the top bit set and so the commands are 80h, c0h, 94h, d4h. So both values are correct.
