Content originally posted in LPCWare by schisanoa on Mon Jan 20 08:38:43 MST 2014 I've now receivd the answer from NXP technical support( very fast answer, very efficient)!
I'll report: Quote: The pins have multiplexers which allows to connect several functions to a single pin. Which function is active can be selected through the IOCON register. This is explained in the UM (www.nxp.com/documents/user_manual/UM10562.pdf), chapter 'Chapter 7: LPC408x/407x I/O configuration'
Now the problem is only on the PINMUX application. Someone know if it possible to manage the problem on the app?(it is useful if possible)
