71 Nano seconds to delay after the SCLK edge before sampling Rx data
72 (may need to be fine tuned for high capacitance lines).

81 Names for the pin configuration(s); may be "default" or "sleep",
82 where the "sleep" configuration may describe the state
83 the pins should be in during system suspend.
