// High frequency ISO15693 commands

+// There are three basic operation modes, depending on which device (proxmark/pc)
+// the signal processing, (de)modulation, transmission protocol and logic is done.
+// Mode 1:
+// All steps are done on the proxmark, the output of the commands is returned via
+// USB-debug-print commands.
+// Mode 2:
+// The protocol is done on the PC, passing only Iso15693 data frames via USB. This
+// allows direct communication with a tag on command level
+// Mode 3:
+// The proxmark just samples the antenna and passes this "analog" data via USB to
+// the client. Signal Processing & decoding is done on the pc. This is the slowest
+// variant, but offers the possibility to analyze the waveforms directly.
