This script will program a T55x7 TAG with the configuration: block 0x00 data 0x000100
The outlined procedure is as following:

--ASK
    00 00 80 40
--           max 2 blocks
--        FSK1
--     bit rate

"lf t55xx write b 0 d 00007040"
"lf t55xx detect"
"lf t55xx info"

Loop:
    change the configuretion block 0 with:
    -xx 00 xxxx = RF/8
    -xx 04 xxxx = RF/16
    -xx 08 xxxx = RF/32
    -xx 0C xxxx = RF/40
    -xx 10 xxxx = RF/50
    -xx 14 xxxx = RF/64
    -xx 18 xxxx = RF/100
    -xx 1C xxxx = RF/128
