Lpc2000

I'm trying to communicate with a AD converter through a SPI interface.
In the AD datasheet, it's said that I need to have DIN line (from AD) in
low level when it's transmitting. This means that I have to write 0x00
on MOSI line while i'm receiving the data. The problem is, there's just
one data register, can I do that? If I can't, can I change just the MOSI
pin to GPIO mode and put on low level while I'm receiving data?
