翻译：When the PHY Master Interface is enabled by setting DFIPHYMSTR.dfi_phymstr_en bit (see UMCTL2_REGS Registers on page 629) and there is a dfi_phymstr_req coming from the PHY. In this case the DDRC's hif_cmd_stall is not driven high (the controller can accept commands on HIF) and existing controller commands in the DDRC are not executed before the entering the Self Refresh mode sequence occurs.

当通过设置DFIPHYMSTR.dfi_phymstr_en位（参见第629页的UMCTL2_REGS寄存器）启用PHY主接口并且PHY发出dfi_phymstr_req请求时。在这种情况下，DDRC的hif_cmd_stall不会被驱动高（控制器可以接受HIF命令），并且在进入自刷新模式序列之前，DDRC中现有的控制器命令不会被执行。
