+I2C protocol decoder.
+
+The Inter-Integrated Circuit (I2C) bus is a bidirectional, multi-master
+bus using two signals (SCL = serial clock line, SDA = serial data line).
+
+There can be many devices on the same bus. Each device can potentially be
+master or slave (and that can change during runtime). Both slave and master
+can potentially play the transmitter or receiver role (this can also
+change at runtime).
+
+Possible maximum data rates:
+ - Standard mode: 100 kbit/s
+ - Fast mode: 400 kbit/s
+ - Fast-mode Plus: 1 Mbit/s
+ - High-speed mode: 3.4 Mbit/s
+
+START condition (S): SDA = falling, SCL = high
+Repeated START condition (Sr): same as S
+Data bit sampling: SCL = rising
+STOP condition (P): SDA = rising, SCL = high
+
+All data bytes on SDA are exactly 8 bits long (transmitted MSB-first).
+Each byte has to be followed by a 9th ACK/NACK bit. If that bit is low,
+that indicates an ACK, if it's high that indicates a NACK.
+
+After the first START condition, a master sends the device address of the
+slave it wants to talk to. Slave addresses are 7 bits long (MSB-first).
+After those 7 bits, a data direction bit is sent. If the bit is low that
+indicates a WRITE operation, if it's high that indicates a READ operation.
+
+Later an optional 10bit slave addressing scheme was added.
+
+Documentation:
+http://www.nxp.com/acrobat/literature/9398/39340011.pdf (v2.1 spec)

+USB (full-speed) protocol decoder.
+
+Full-speed USB signalling consists of two signal lines, both driven at 3.3V
+logic levels. The signals are DP (D+) and DM (D-), and normally operate in
+differential mode.
+The state where DP=1,DM=0 is J, the state DP=0,DM=1 is K.
+A state SE0 is defined where DP=DM=0. This common mode signal is used to
+signal a reset or end of packet.
+
+Data transmitted on the USB is encoded with NRZI. A transition from J to K
+or vice-versa indicates a logic 0, while no transition indicates a logic 1.
+If 6 ones are transmitted consecutively, a zero is inserted to force a
+transition. This is known as bit stuffing. Data is transferred at a rate
+of 12Mbit/s. The SE0 transmitted to signal an end-of-packet is two bit
+intervals long.
