Commands listed in alphabetical order
Arguments
FALLING
decodes on the falling edge of the clocked parallel bus signal.
RISING
decodes on the rising edge of the clocked parallel bus signal.
EITHER
decodes on the rising or falling edge of the clocked parallel bus signal.
Examples
BUS:B1:PARALLEL:CLOCK:EDGE FALLING
sets the decoding to happen on the
falling edge of its clocked parallel bus B1.
BUS:B1:PARALLEL:CLOCK:EDGE?
might return
:BUS:B1:PARALLEL:CLOCK:EDGE RISING
, indicating that when bus B1
operates in Clocked Parallel mode, it samples new data values on the rising edge
of its clock source signal.
BUS:B<x>:PARallel:CLOCk:ISCLOCKED
This command determines whether the bus operates in a clocked or asynchronous
fashion. The bus is speci
fi ed by x.
Group Bus
Syntax
BUS:B<x>:PARallel:CLOCk:ISCLOCKED {OFF|ON|NR1>
BUS:B<x>:PARallel:CLOCk:ISCLOCKED?
Arguments
OFF
argument speci fi es an asynchronous bus.
ON
argument speci fi es a clocked bus.
<NR1>
= 0 speci fi es an asynchronous bus; any other value speci fi es a clocked bus.
Examples
BUS:B1:PARallel:CLOCk:ISCLOCKED 0
sets the bus to operate
asynchronously.
BUS:B1:PARallel:CLOCk:ISCLOCKED?
might return
:BUS:B1:PARALLEL:CLOCK:ISCLOCKED 1
indicating the bus is
clocked.
BUS:B<x>:PARallel:CLOCkSOUrce
This command sets or queries the Parallel clock bit source for the speci fi ed bus.
The bus is speci fi ed by x.
