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

"lf t55xx write 0 00088040"
"lf read"
"data samples"
"data pskdet"
"data psknrz"
"data pskindala"
"data psknrzraw"

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
			XXXXX8XX = PSK RF/8

In all 12 individual test for the PSK demod

Arguments:
