Timer; Pattern Counter - Teledyne Sierra M6-2 User Manual

Trainer Script Enhancements
When there are variable values in RawData, you must include SendCRC command instead
of last DWORD. Otherwise, wrong CRC value will be sent.
The constraints are:
If SATA_CRC command is not included, trainer engine computes and inserts correct CRC in
pattern.

5.13.6 Timer

Trainer script syntax allows using some timers. You can start a timer anywhere. The timer
