-/* Provides a framework for bidirectional LF tag communication
- * Encoding is currently Hitag2, but the general idea can probably
- * be transferred to other encodings.
- *
- * The new FPGA code will, for the LF simulator mode, give on SSC_FRAME
- * (PA15) a thresholded version of the signal from the ADC. Setting the
- * ADC path to the low frequency peak detection signal, will enable a
- * somewhat reasonable receiver for modulation on the carrier signal
- * that is generated by the reader. The signal is low when the reader
- * field is switched off, and high when the reader field is active. Due
- * to the way that the signal looks like, mostly only the rising edge is
- * useful, your mileage may vary.
- *
- * Neat perk: PA15 can not only be used as a bit-banging GPIO, but is also
- * TIOA1, which can be used as the capture input for timer 1. This should
- * make it possible to measure the exact edge-to-edge time, without processor
- * intervention.
- *
- * Arguments: divisor is the divisor to be sent to the FPGA (e.g. 95 for 125kHz)
- * t0 is the carrier frequency cycle duration in terms of MCK (384 for 125kHz)
- *
- * The following defines are in carrier periods:
