Hi Uno-san,
Thank you very much for your report. Yes, you are right. There are extra IOCON settings for specific functions of LPC11xx.

The updated mbed library hasn't been released yet.
You can use latest mbed-src libray (rev 425 or lator) instead. http://developer.mbed.org/users/mbed_official/code/mbed-src/rev/73631a54077f
