+ *
+ * Pin attribute settings match the hardware register definitions very
+ * closely, and as such are specified in a chip-specific format.  C-language
+ * pre-processor macros are provided to allow for as much code readability
+ * and maintainability as possible. Because the organization and the
+ * electrical fine-tuning capabilities of the pins may change between
+ * products, ODMs should ensure that they are using the macros that match
+ * the SOC in their product.
