System Synchronization Interface
（
SSI
）
for PCIe Modules
The synchronization between PCIe modules are handled differently from the PXIe
synchronization, it is implemented by the system synchronization interface (SSI). SSI is
designed as a bidirectional bus and it can synchronize up to four PCIe modules. One
PCIe module is designated as the master module and the other PCIe modules are
designated as the slave modules.
