Commands listed in alphabetical order

Arguments

FALLING decode

s 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:EDG E FALLING sets the decoding to happen on the

falling edge of its clocked parallel bus B1.

BUS:B1:PARALLEL:CLOCK:EDG E? might return

:BUS:B1:PARALLEL:CLOCK:ED GE 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 opera tes in a clocked or async hronous

fashion. The bus is speciﬁed by x.

Syntax

BUS:B<x>:PARallel:CLOCk:I SCLOCKED {OFF|ON|NR1>

BUS:B<x>:PARallel:CLOCk:I SCLOCKED?

Arguments

OFF argument speciﬁes an asynchronous bus.

ON argument speciﬁes a clocked bus.

<NR1> =0speciﬁes an asynchronous bus; a ny other value speciﬁes a clocked bus.

Examples

BUS:B1:PARallel:CLOCk:ISC LOCKED 0 sets the bus to operate

asynchronously.

BUS:B1:PARallel:CLOCk:ISC LOCKED? might return

:BUS:B1:PARALLEL:CLOCK:IS CLOCKED 1 indicating the bus is

clocked.

BUS:B<x>:PARallel:CLOCkSOUrce

This command sets or queries the Parallel c lock bit source for the speciﬁed bus.

The bus is speciﬁed by x.
