UNUSED PINS OF A PERIPHERAL

Hi,

when I use a peripheral with some unused pins, can I use other alternate functions of those pins (for other peripherals)?
for example, in STM32f407, I use SPI2 with unused SPI2_NSS (pin 140). can I use this pin as I2C1_SDA (SPI2_NSS and  I2C1_SDA are both defined as alternate functions for pin 140 in datasheet)?

thanks
