/** I/O pins.

  In MBED, I/O pin handling is rather complicated. Lots of enums, lots of
  functions, spread over various files, slow execution (pin toggling about
  15 times slower than what we have here).

  Accordingly, the strategy for FastIO is derived directly from the data sheet.
  There one can see that hardware is very similar to that of AVRs: pins grouped
  in ports (here: 12 pins per port) and a number of additional registers with
  bits for additional proterties: wether input or output, wether a pullup is
  attached, and so on. See chapter 12 of the LPC111x User Manual. Other than
  AVRs, many ARMs (including the LPC1114) support bit-banding, which is
  interrupt safe and also a few clock cycles faster. See macros in pinio.h.
