Alsig, If you write a byte to the transmit register the SCK clock should be generated. Make sure the SPI1 peripheral is enabled and powered (Check PCONP bits). You should be able to do your initial test using your debugger and the direct access to the control registers. Also, only the MISO pin should show as an input, MOSI and SCK should be outputs driven SPI. Once you are past the clock and MOSI hurdle you'll need the slave select signal from your LPC to the EE and the right SPI mode (CPOL and CPHA) for proper data access. I hope it helps.
