ADLINK PCIe-7350 - Manual (Page 80)

70 Function Block and Operation Theory
Figure 3-39 is an example of 9 channel (CH0 – CH8) pattern
match operation. All of the enabled DI channel’s signal logic states
will be compared with the user-defined pattern "1100RRFFX". The
pattern match event and interrupt will be generated while the fol-
lowing conditions are all matched:

CH0 and CH1 are logic high

CH2 and CH3 are logic low
 CH4 and CH5 are rising edge
 CH6 and CH7 are falling edge
 CH8 is ignored
Note: For PCIe-7350, the edge detection (rising or falling) compare
the currently sampled data with the previously sampled data.
