CPM block contains two controllers. A transition from low to high will indicate that power Any PCIe interface has two kinds of diffpairs – TX and RX; for an x1 link, you will have one TX diffpair and one RX diffpair, and a x16 link needs sixteen of each. Implementing function-level resets is not required by the PCIe specification.
