+/////////////////////////////////////////////////////////////////////////////
+//
+// Outputs 32-bit words of data
+// Only works down to 396MHz (see explanation below)
+//
+// This is an SPDIF receiver. It needs 1 thread and no memory other
+// than ~2800 bytes of program code. It can do 11025, 12000, 22050, 24000,
+// 44100, 48000, 88200, 96000, and 192000.
+//
+// Its "elegance" is in the implementation method. The signal is sampled at
+// 50 Mhz (assuming 192000, which is 12 Mbps), and the bits that come in are
+// used to drive a parser. I gratuitously used assembly (all machine generated)
+// in order to build a state machine that goes through 5 steps:
+// 1) IN 4 seralised bits from the SPDIF PHY
+// 2) BRU to these bits (that is, add the value inputted to the program counter)
+// 3) BL to the code that deals with the state transition
+// 4) Perform an LMUL to add 0/1  bits to the received word
+// 5) IN the next 4 serialised bits.
+// 6) If an error is encountered, then up a binary counter on the leds and
+// record the erroneous part of the stream.
+//
+// The program needs 40-60 ns to deal with 4 samples, and 80-100 ns to deal
+// with the final sample which limits the speed to 12 Mbps or 192,000 samples/s
+// stereo. There are around 80 states, each with a 16-long jumptable.
+//
+// The bit streams are 3.072, 6.144, or 12.288 Mbits/s - we sample them at
+// 12.5, 25, or 50 MHz.
+// So we get "4.something" samples per bit.
+//
+// Normally samples 0000/1111 mean '0' and 0011/1100 mean '1'. Any other value
+// means 'Error'. However, since it is slightly more than 4, it could be '00000'
+// rather than '0000'. Hence, if you sample four bits at a time, you slowly go
+// out of sync. The code implements a state machine; state '000' means 'I have
+// seen three zeros that I haven't decided what to do with' So if you then
+// read samples '0111' then you know that you have seen a logical '0' (0000),
+// and you go to state '111' because there are still three ones to deal with.
+// So, if your clock is too low, you will sample sometimes only 3 times per bit,
+// and you are toast. You can run it at, say, 360 Mhz, but you will have to
+// divide the clock by 7 to get a 51.4 MHz clock... Or divide the 90 Mhz clock
+// by 3 to get a 30 MHz clock that can sample 96 KHz. There is also a subtlety
+// that rise and fall times are not equal, and hence '0111' and '1110' are
+// actually ones.
