+NEC infrared protocol
+------------------------------------------------------------------------
+
+These captures were taken with the "Joy-IT SBC IR01" remote control. File
+joy_it_sbc_irc01_all.sr contains data for all the buttons of that remote.
+File joy_it_sbc_irc01_enter_no_repeat.sr contains a single button that gets
+pressed repeatedly, but for a short period of time such that the remote
+won't send a repeat signal (each button press is new).
+
+There are several interesting aspects to these files:
+- The signal would not decode with 5% tolerance. A wider limit is needed
+ because this remote control's signal is outside of that narrow window.
+- The absence of IR frames for repeated button press could reveal an issue
+ with earlier decoder implementations, where the emission of annotations
+ for an IR frame was deferred until the start of the next IR frame.

+Siemens SLE44xx Chip Card Protocol
+------------------------------------------------------------------------
+
+SLE 4418/4428/4432/4442 memory cards implement a 2-wire protocol for data
+communication (signals CLK and I/O). A RST signal can be used to terminate
+currently pending long memory reads, and resets the card's address counter
+when combined with CLK. The next response data then is the Answer to Reset
+(ATR) which identifies the chip's capabilities, and allows to adjust for
+subsequent communication of more requests.

+SQI communication (multi-I/O SPI)
+------------------------------------------------------------------------
+
+This capture demonstrates SQI communication, which is a form of SPI data
+exchange where transmitters use multiple I/O data lines in parallel to
+communicate the same amount of data in fewer clock cycles.
+
+In contrast to e.g. QuadSPI flash memory chips which may change the data
+line count or clock scheme several times within a transaction, SQI keeps
+the clock and the number of data lines used by the transmitter consistent
+across the full length of the SPI transaction. Only the direction of data
+lines could change, when e.g. a master first transmits a request which
+the slave then responds to, while both use the same number of data lines.
+Full duplex communication as with the traditional MISO/MOSI scheme is
+not possible with SQI.
