This is the exclusive or operation,
0^0 = 0
0^1 = 1
1^0 = 1
1^1 = 0
the variables temp and lcd_DATA are exclusive ORed bit by bit (bit0 with bit0, bit1 with bit1 etc)
usually this kind of operation is used to invert one or more bits,
anything exclusive ORed with 1 is inverted (a 0 becomes 1, and 1 becomes 0)

I don't see, that you setup the pin configuration according to the mikroC manual. Apparently you're not using the default pin assignments for the expander interface, then the assignment expected to be specified with the SPI_lcd8_Config() command.

Bjuric is correct.
You should be able to toggle the direction of RB0 and RB1 while ensuring the port pin tied to the lcd E line is held low. If you post or upload your code, we should be able to make a few changes to allow for the lcd's proper operation.

If you apply power to the lcd, with the contrast pin grounded, the display usually shows a single line of block characters. That means it is powered correctly and is basically functional. If you have a contrast potentiometer already connected just turn it all the way down to see the single line of blocks.
If the lcd still looks like that (...)

What does not work in real hardware? Do you not see anything in the lcd? Or is the time-keeping erroneous? Did you use a 32.768kHz crystal as required? Did you connect a battery? If you need battery backup, you must connect a battery, if not, the pin should be shorted.
