Multi-function pins on LPC1343

I'm using an LPC1343 and one of the digital GPIO outputs doesn't work. We're not using the SPI or UART, but PORT0_8 doesn't seem to work like the other digital outputs that are on single function I/O pins. It must be due to configuration, but I just don't seem to see any such configuration code in any of my documentation or sample programs. Any pointers would be greatly appreciated.

Found the problem. Using timer16_0, the init call configures this pin as a timer input....

Commented line out, now it works as standard I/O....
