This may be a dumb question, but I would like to set up pointers in Flash memory to the configuration registers for the I/O on an LPC1114 processor, e,g. registers of the form LPC_IOCON->PIO0_1. Is this possible.?

Hello,

The multiplexed pins most certainly can be structured to be user friendly and readable in the way you are mentioning. In fact, our software platform called LPCOpen provides software examples that structure things in this way, as well as easy API calls. Here's a link to the LPCOpen downloads:

Even if your board is not supported, it would be helpful to look at the way things are declared. A quick glance at the UART example shows that the registers can be indirectly accessed like so: pIOCON->PIO0[pin].
