  35          * This library modul is written for a C166 microcontroller derivative.
  36          * The source can be ported to other platforms very easily. 
  37          * The communication channel to the RC500 reader IC is assumed to be 
  38          * unknown. All data is written with the generic IO functions 
  39          * of the module RcComunication.h (Reader core communication). 
  40          * In our case the reader module is 
  41          * connected via memory mapped io at base address 0x100000.
  42          * The interrupt pin of the reader IC is assumed to be connected to 
  43          * the fast external interrupt pin INT0# (active low) and the reset
  44          * pin of the reader IC should be connected to a dedicated port pin
  45          * (Port: P1 Pin: 9).
  46          * In this configuration, a reset of the reader module is independend
  47          * from the reset of the microcontroller.
  48          * In order to generate communication timeouts, 
C51 COMPILER V6.12  MFRC500UC                                                              08/18/2008 15:29:35 PAGE 2   

  49          * general purpose timer 3 of the microcontroller is used. This 
  50          * timer need not to be initialised in advance. Before every usage 
  51          * the timer is completely initialised in each function. 
  52          * Non of the timers is essential for the functionality of the reader
  53          * module, but are helpful furing software development. All protocoll 
  54          * relevant timing constraints are generated
  55          * by the internal timer of the reader module.
  56          * 
  57          * Some explanations to the programming method of this library.
  58          * There are three kind of functions coded in this module.
  59          * <ol>
  60          *  <li> internal functions, which have no prototypes in a header
  61          *       file. This kind of functions are not intended to be used 
  62          *       outside of this file
  63          *  <li> commands, which are intended for the reader module itself
  64          *  <li> commands, which are intended for any tag in the rf field.
  65          *       These commands are send to the reader and the reader module
  66          *       transmitts the data to the rf interface.
  67          * </ol>
  68          * Commands for the reader and for the tag have the appropriate 
  69          * prefix (PCD for Proximity Coupled Device or reader module
  70          * PICC for Proximity Integrated Circuit Card or tag)
  71          * and their protypes are defined in the header file.
  72          * Certainly, each command for a PICC consists of an instruction to the PCD. 
  73          * Therefore
  74          * the function PcdSingleResponseCmd is very important for the understanding
  75          * of the communication.
  76          * 
  77          * The basic functionality is provided by the interrupt service
  78          * routine (SingleResponseCmd), which closely works together with the function
  79          * PcdSingleResponseCmd. All kinds of interrupts are serviced by the 
  80          * same ISR.
