16enable foreground and background change
When enabled the cursor changes the shown attributes of the cell it is on.
Some drivers force size = 1 (none) internally if this is set.
32ensure orginial background and cursor background differ.
If the original and cursor background would be identical invert all background color channels (but not brightness).
64ensure cursor foreground and background differ.
If the cursor background and foreground would be identical invert all foreground color channels (but not brightness).

Together xor and or define changes to foreground and background of the cell where the cursor is shown when flags has that feature enabled. Each bit in both parameters describes one aspect to change. The effective change depends on that bit in both.
