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
--        manchester
--     bit rate
 
"lf t55xx write 0 00008040"
"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
