Currently shipped screens have the R9 resistor fitted. If the back of your LCD looks like this...

...with a 0R resistor soldered to R9 then your module will be fixed to parallel mode. If you need to use it in serial SPI mode you will need to remove this resistor and then connect the PSB pin to GND. Alternativly you can just move the resistor from R9 to R10.
