At a little bit of a lost here..  I'm not using MQX just some simple, I thought, GPIO writing and reading.  I seems to not clearly under stand the data sheet. 



IOMUXC->SINGLE.PTC15 =  0x1D;  // set as input with 47K pull up on PTC15


rd = GPIO1->PDIR;       // read and bit 28 I think is PTC15 and it should be HIGH



what am I missing..
