I'm trying to configure PIO0_8/ADC0_0/TDO as a SPI data pin however it doesn't seem to be working (clock works on another pin). Is there a problem with using this pin for SPI or could I be unknowingly putting the part (LPC1547) in boundary scan mode? How can I be sure the part isn't in a debug/boundary scan mode?
I think you are trying to get something from pin PIO0_8 when (according to your text) it is not part of the SPI peripheral. (MOSI stands for Master Out, Slave In.)
