}
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:
 Variables are not allowed on First and LAST DWORD (instead of start/end
frames).
 SendCRC is only supported on last DWORD before end of frame.
SendSATAFrame
{
SATA_SOF
SATA_DATA ( 0x11223344 )
SATA_DATA (@variableName1)
SATA_DATA ( 0x55667788 )
#SATA_CRC ( 0x99AACCBB ) # good crc - can be changed to bad
SATA_EOF
}
If SATA_CRC command is not included, trainer engine computes and inserts correct CRC in
pattern.
Timer
Trainer script syntax allows using some timers. You can start a timer anywhere. The timer
current value is loadable on variable to be used in expressions and conditions on this
expression. There are four timers, named A, B, C, and D.
Starting timer (setting timer value to zero) syntax is:
CLEAR_TIMER_A
CLEAR_TIMER_B
CLEAR_TIMER_C
CLEAR_TIMER_D
Loading timer current value in variables:
@varName1 =TIMER_A
@varName1 =TIMER_B
@varName1 =TIMER_C
@varName1 =TIMER_D
