SSP dual / quad data output on i.MX233?

I'm struggeling in getting dual / quad SSP data output from the i.MX233. According to the processor architecture it should be possible in Winbond SPI mode, but I found in the i.MX233 manual no information about the data line assignment. You can set Winbond mode and enable dual / quad mode in the SSP processor registers, but can't tell the i.MX233 on which pins to output that dual / quad data. How can this be achieved?
(According to the pin description in the i.MX23 manual data for SSP2 should be output on bank 0, pins 0 - 7. In no case I could measure any output on these pins in Winbond SPI mode with dual / quad mode enabled, data ist only output on SSP2_CMD (bank 0, pin 20)).
