H A Dreg_addr.h847 #define PCIEIP_REG_LINK_CAPABILITIES_REG_PCIE_CAP_L1_EXIT_LATENCY_K2 (0x7<<15) // L1 Exit Latency. There are two each of these register fields, this one and a shadow one at the same address. The Common Clock bit (PCIE_CAP_COMMON_CLK_CONFIG) of the Link Control Register (LINK_CONTROL_LINK_STATUS_REG) determines which one is used by the core and which one is accessed by a read request. Common Clock operation is supported (possible) in the core when one or more of the following expressions is true: - CX_NFTS !=CX_COMM_NFTS - DEFAULT_L0S_EXIT_LATENCY !=DEFAULT_COMM_L0S_EXIT_LATENCY - DEFAULT_L1_EXIT_LATENCY !=DEFAULT_COMM_L1_EXIT_LATENCY Common Clock operation is enabled in the core when you set the Common Clock bit (PCIE_CAP_COMMON_CLK_CONFIG) of the Link Control Register (LINK_CONTROL_LINK_STATUS_REG). The assertion of CS2 (that is, assert the dbi_cs2 input, or the CS2 address bit for the AXI bridge) is required to write to the shadow field at this location. Note: The access attributes of this field are as follows: - Dbi: if (DBI_RO_WR_EN == 1) then R/W else R macro
