PIPE在上电时Gen1/Gen2中配置。Gen3 PCS配置为8 Gbps。

39 当使能简化的数据接口时,请参考来了解相关的比特设置。
40 设置此参数是依赖布局的。在AUTO模式下,Native PHY IP Parameter Editor将选择配置的最中间通道作为默认的PCS TX channel bonding master。您必须确保此被选通道一定要布局成收发器bank的Ch1或Ch4。此外,对PCS TX channel bonding master使用手动选择,选择一个能够布局成收发器bank的Ch1或Ch4的通道。关于详细信息,请参考“如何对PIPE配置布局通道”部分。
41 上电期间PIPE在Gen1/Gen2中配置。对于32的PCS/PMA宽度配置Gen3 PCS。
