3.4.1. MIPI I/O Bank Sharing with External Memory Interface Protocol

You can share I/O banks between MIPI D-PHY IPs and external memory interfaces (EMIFs) to optimize the device resource utilization. The tables show the allowed I/O sharing when MIPI D-PHY IPs are sharing the same I/O bank with EMIFs. No I/O sharing is allowed between MIPI D-PHY IPs with DIMM based EMIF. The I/O bank sharing rules are stricter on HPS EMIF (while using F2H bridge or the F2SDRAM bridge, or both bridges). For more information on I/O bank sharing for HPS EMIF implementations, refer to the External Memory Interface User Guide.
Table 15.  MIPI Implementation that does not Require RZQ Sharing with Fabric and HPS EMIF

HPS EMIF is without F2SDRAM or F2H bridge usage. For HPS EMIF restrictions, refer to the External Memory Interface User Guide.
