"Frame start
(Timeout)"
Triggers on the start of the frame when the clock idle time exceeds the
"Timeout" time. This trigger type is available if Frame condition is set to
"CLK timeout".
"MOSI"
Sets the trigger to a specified data pattern expected on the MOSI line.
See: "MOSI and MISO data conditions" on page 275.
"MISO"
Sets the trigger to a specified data pattern expected on the MISO line.
See: "MOSI and MISO data conditions" on page 275.
"MOSI/MISO"
Sets the trigger to specified data patterns expected on the MOSI and
MISO lines.
SCPI command:
TRIGger<m>:SPI:MODE on page 668
MOSI and MISO data conditions
The trigger on MOSI and MISO patterns is defined in the same way:
Condition ← MOSI and MISO data conditions
Selects the operator for the "Data" pattern: "Equal" or "Not equal".
SCPI command:
TRIGger<m>:SPI:FCONdition on page 670
MOSI pattern, MISO pattern ← MOSI and MISO data conditions
Specifies the data pattern to be found on the MOSI or MISO line, respectively. Enter the
words in msb first bit order. The maximum pattern length is 256 bit if one pattern is defined.
If both MOSI and MISO patterns are used, the maximum pattern length of each pattern
is 128 bit. The starting point of the pattern is defined by Index min, Index max and Search
mode.
The bit pattern editor helps you to enter the pattern, see chapter 10.1.4, "Bit Pattern
Editor", on page 255.
