WriteMapping()
{
  // Create the RCU mapping files for PHOS
  // The geometrical mapping within one FEE card is read
  // from the file CSP2ALTRO.dat prepared manually beforehand.
  //
  // The hardware address of the FEE channels is a 12-bit word formed 
  // from the branch number, FEE number, ALTRO chip number and ALTRO channel
  // as follows:
  // +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
  // |0|0|0|0| |       |     |       |
  // +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
  //          ^   FEE    chip  channel
  //       branch
  //
  // Max address: 1 1110 100 1111 = 3919
