PCIe1 instance on J7AHP EVM EP connector has reference clock connection from serdes unlike PCIe0 for which reference clock connection is from on-board clock generator. To enable PCIe1 instance, ACSPCIE clock buffer pads have to be enabled to get reference clock output available to PCIe1 EP This enables clock source select and ACSPCIE clock buffer pads.
