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

"lf t55xx write b 0 d 00088040"
"lf t55xx detect"
"lf t55xx info"

Loop OUTER:
    change the configuretion block 0 with:
    -xxxx8xxx = PSK RF/2 with Manchester modulation
    -xxxx1xxx = PSK RF/2 with PSK1 modulation (phase change when input changes)
    -xxxx2xxx = PSK RF/2 with PSk2 modulation (phase change on bitclk if input high)
    -xxxx3xxx = PSK RF/2 with PSk3 modulation (phase change on rising edge of input)
    Loop INNER
        for each outer configuration, also do
            XXXXX0XX = PSK RF/2
            XXXXX4XX = PSK RF/4
