/**
 * This is a crude hack that works, in the absence of generic
 * componts. The identifiers for the sfr registers needs to be
 * globally defined and I cannot come up with a way to pass a
 * reference to these identifiers through a generic compontnt
 *
 * The purpose of this file is mostly to show a working example for
 * 8051 variants. The particular chips are likely to diverge from
 * these definitions, in particular in the number of pins, but also
 * features such as tristating the pins (for exmple cc2430 supports
 * this).
