The standard seems to call it "Loss of framing". To me as a network
person, a frame is an L2 Ethernet packet. However, framing is
something completely different, being able to synchronise a bitstream
with some sort of markers, e.g. E1 to know where the 32 slots are.

In this context, we are not talking about packets, but the SPI bit
stream. So it would be good to use framing, not frame.
