Single Bit Trigger a 2-entry list indicator by setting or clearing a bit at the
read tag address. The number of states must be set to 2
before the single bit option is available.
Least Significant Bit Trigger multiple entries. Entries display in a sequence
corresponding to bits set at word address(es) starting with the
read tag address.
The tag data type for least significant bit is unsigned integer.
Value Trigger a list entry based on a value at the read tag address.
Each entry is linked to a different value.
Note: If using more than 16 entries for the Least Significant Bit
(LSB) trigger, reserve up to 15 consecutive word addresses after the
tag address. Every 16 entries = 1 word address, with up to 255 total
entries. The LSB will only use up to the word of the last entry.
For the Value option, you must select the format of the data from the
Data Format list box. The data type of the read tag must be
compatible with the selected format for the application to validate.
