3.10 Pattern Match
PCIe-7360 supports pattern match function to monitor the data
input lines that conform to the user-defined pattern (for example,
10101110). When the data lines conform to the user-defined pat-
tern, PCIe-7360 will generate a pulse signal of pattern match
event to the AFI pin and generate the pattern match interrupt to
host PC as well.
Below are the conditions of pattern match. The pattern match can
be a single change of specific data line or a combination of differ-
ent data lines.
Logic State Description
0 Match on a logic low level at the input channel
1 Match on a logic high level at the input channel
R Match on rising edge at the input channel
F Match on falling edge at the input channel
X Ignore the input channel
