+LFAST is a physical communication interface used mainly by the NXP ZipWire
+interface. It's a framed asynchronous serial interface using differential
+TX/RX pairs, capable of data rates of up to 320 MBit/s.
+
+This interface is also provided by Infineon as HSCT.
+
+As with most differential signals, it's sufficient to measure TXP or RXP, no
+need for a differential probe. The REFCLK used by the hardware isn't needed by
+this protocol decoder either.
+
+For details see https://www.nxp.com/docs/en/application-note/AN5134.pdf
