1024, the counter is 10 bit wide. You can also display that $c0 bytes, which is not visible from the bitmap by default.
Just inc your own 16 bit counter and write it to $ff1b/1a before the screen starts.
The lower byte is the $ff1b. and $ff1a only uses the lower 2 bits, so you can write anything to the upper bits.
