GPIO-HSTC Card - voltage level

Hi,

I have a question regarding the THDB-HTG-Card: If I set the input voltage of the HSTC pins to say 1.5 V, will the output voltage of the GPIO pins also be 1.5 V? Or is the Voltage affected by the card?

Specifically I want to put the following card on a SoCKit board:

Then I want to set the output level of the HSTC pins of the SoCKit board to 1.5 Volts (via Jumper JP2). Will the output Voltage I get on the GPIO pins of the card also be 1.5 V?

Regards
