Teledyne LeCroy PETrainer Scripting Language

10 Loop Command

This command causes the PETrainer™ BusEngine™ to re-execute a block of commands a predefined

number of times.

Note: Loops require up to 1 us to branch to the beginning of the loop. During this time, script execution is

paused. Internally generated packets, such as SKIP ordered sets, Ack/Nak DLLP packets, and flow

control updates, still occur as programmed.

Loops can be nested up to 4 deep (up to 8 deep for the Summit Z2-16 and Summit Z3-16 Trainers).

10.1 Loop = Begin

This command marks the beginning of the loop.

Packet = TLP { TLPType = CfgRd0 Length = 1 Register = 0 }
