  14 This script will program a T55x7 TAG with the configuration: block 0x00 data 0x00088040
  15 The outlined procedure is as following:

  17 "lf t55xx write 0 00088040"
  18 "lf read"
  19 "data samples"
  20 "data pskdet"
  21 "data psknrz"
  22 "data pskindala"
  23 "data psknrzraw"
  24
  25 Loop OUTER:
  26         change the configuretion block 0 with:
  27     -xxxx8xxx = PSK RF/2 with Manchester modulation
  28     -xxxx1xxx = PSK RF/2 with PSK1 modulation (phase change when input changes)
  29     -xxxx2xxx = PSK RF/2 with PSk2 modulation (phase change on bitclk if input high)
  30     -xxxx3xxx = PSK RF/2 with PSk3 modulation (phase change on rising edge of input)
  31         Loop INNER
  32             for each outer configuration, also do
  33                         XXXXX0XX = PSK RF/2
