+  NOTE:

+  1. It is not possible to use any of the SPI devices on the Shield unless
+     a bit-bang SPI interface is used.  This includes the touch controller
+     and the SD card.
+  2. UART0 cannot be used
+  3. Parallel data is not contiguous in any PIO register
+  4. 3.3V and 5V are reversed.
