15.2.13.2 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.

.
1..4
Selects the bus.
Note: SPI/SSPI and UART protocols occupy two bus lines.
Parameters:
<Source> CH1 | CH2 | CH3 | CH4 | D0..D15
*RST:  CH1
BUS<b>:SPI:CS:POLarity <Polarity>
Selects whether the chip select signal is high active (high = 1) or low active (low = 1).
Suffix: 
<b>
.
1..4
Selects the bus.
