Remote command:
Adress Type
Sets the address length to be triggered on: 7 bit, 7+1 bit, or 10 bit. Available settings
depend on the
setting of the bus configuration.
For "7 bit" and "10 bit", enter the address bits in the
field, and use the
on page 503 field to select the transfer direction.
For "7+1 bit", enter the seven address bits and also the R/W bit in the "Address" field.
If the trigger type is "A data", you can set the address type "Any" to trigger on
data only, regardless of the address.
Remote command:
TRIGger<m>:I2C:ADOR<n>:ADRType
Address
The trigger address setup consists of a comparison condition and one or two address
patterns.
Defines the bit pattern of the secondary device address. The length of the entry is
adjusted to the selected address type.
In binary format, use the following characters: 1; 0; or X (do not care). To enter the pat-
tern in other formats use the bit pattern editor, see
Chapter 13.1.7, "Bit pattern editor"
"Condition"
Sets the comparison condition to a specific value or a range.
"Min"
Specifies the value or sets the start value of a range.
"Max"
Sets the maximum value of a range for "Condition" = "In range"/"Out
of range".
Remote command:
TRIGger<m>:I2C:ADOR<n>[:VALue]
R/W bit
Toggles the trigger condition between read and write access of the primary. Select
