7.4 Interface Input/Output Test (IOTEST)
This command is used to test both the input and output data busses of the
signal processor interface. When issued, the command causes sixteen
words to be read from the host controller, after which those same sixteen
words are written back out. Typically, the controller supplies a "barber
pole" input sequence consisting, for example, of successive powers of two.
If all of the output words are correct, one may conclude that there are no
malfunctioning bits in the interface hardware.
