17.3.10.17 PCI Express Subsystem Vendor ID Update Register (EP Mode
The PCI Express subsystem vendor ID update register, shown in
for the Subsystem ID and Subsystem Vendor ID registers in the Type 0 configuration header.
The fields of the PCI Express subsystem vendor ID update register are described in
When used as an endpoint, the controller’s initialization software programs the desired subsystem ID and
subsystem vendor ID values in PEX_SSVID_UPDATE before setting the CFG_READY bit in the
PEX_CFG_READY register (see
way, when the host begins system enumeration, the correct values are present in the Type 0 configuration
header.
17.3.10.18 Configuration Ready Register—0x4B0
The PCI Express configuration ready register, shown in
complete status to the transaction layer. The transaction layer handles configuration requests from external
hosts only after the CFG_READY bit is set. All the configuration requests received from external hosts
before the CFG_READY bit is set are completed with configuration request retry status (CRS). The
CFG_READY bit in this register should be set after all relevant configuration registers have been
programmed. This makes sure the external host reads the correct capability advertisements during
enumeration.
Note that the state of PEX_CFG_READY[CFG_READY] is dependent upon the POR configuration
setting described in
