SPI

The Serial Peripheral Interface SPI is used for communication with slow peripheral devi-
ces, in particular, for transmission of data streams. A 4-channel instrument is required
for full support of the SPI protocol.

The SPI/SSPI protocol require two bus lines (bus 1 and 2 or bus 3 and 4), so the number
of buses (suffix <b>) is reduced. Bus 2 and/or bus 4 is not available.
