而对于进出 P2 状态,或者其他 PCLK 不再保持运行状态的 PHY 专用状态时,MAC 必须等到 PHY 表示状态已经切换完成后,再进行需要 PCLK 的操作(Operational sequence)或者后续的电源状态切换。 下面讨论了如何将 PHY 电源状态(译注:Px)映射到协议规定的 LTSSM 链路状态中(译注:Lx)。只要 MAC 满足 PCI Express Base ...
当进入或者离开LPM或者ULPM或者HSCM时, clock lane 处于LPM。在这些不同的情况下,clock lane就会有不同的sequence。 LOW POWER MODE(LPM) 有三种不同的情况可以进入LPM: a) SW reset, HW reset或者Power On Sequency –> LP-11 b) 当离开ULPM时LP-00 -> LP-10 -> LP11,如下图: c) 当离开HSCM时,...

You must add a Transceiver PHY Reset Controller IP core to your design, and connect it to the RapidIO II IP core reset signals. This block implements a reset sequence that resets the device transceivers correctly. In the Transceiver PHY Reset Controller parameter editor, you must perform the fo...

MIPI的D-PHY规定,一个Data Lane进入 High-Speed的方式为发送一个Start-Of-Transmission Sequence即 SOT 信号,这个 SOT 信号的组成为: 即,顺序设置 LP-11、LP-01、LP-00、HS-0、发送 HS Sync 00011101序列,然后发送数据; 发起了 High-Speed Transmission 后,如何停止呢?这里 MIPI 定义了一个和 SOT 对应的破...
