14This script will program a T55x7 TAG with the configuration: block 0x00 data 0x00088040
15The outlined procedure is as following:
16
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
25Loop 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
34 XXXXX4XX = PSK RF/4
35 XXXXX8XX = PSK RF/8
36
37In all 12 individual test for the PSK demod
