What is the FX3 initial state of GPIO if FX3 has not been programmed? tristated?

What is the FX3 initial state of GPIO if FX3 has been programmed and not been assigned a high or low?

I use CY3014, recently I find GPIO45 output a high when my board is new and the FX3 has not been programmed. I connect the GPIO45 with a pull-down resistor of 1K ohm, but GPIO45 has not been pulled down.
