If you use a clocked parallel bus, in the last two lines you can select the source for the
"Clock" and "CS".
Remote command:
BUS<b>:PARallel:DATA<m>:SOURce
on page 775
BUS<b>:CPARallel:DATA<m>:SOURce
on page 775
BUS<b>:CPARallel:CLOCk:SOURce
on page 776
BUS<b>:CPARallel:CS:SOURce
on page 776
Set to Default
Resets the data lines of the parallel bus to the default order D0...D15.
Chip Select
Enables the chip select line for the parallel clocked bus.
Remote command:
BUS<b>:CPARallel:CS:ENABle
on page 776
Polarity
For the parallel clocked bus, selects if the chip select signal is high active ( high =
1) or low active ( low = 1).
Remote command:

on page 777
Slope
For the parallel clocked bus, selects if the data is sampled on the rising ( ) or falling
( ) slope of the clock, or on both edges ( ) of a double data rate clock. The clock
slope marks the begin of a new bit.
