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.
