The PCI configuration register 11 (PCICONF11) is a 32-bit read/write register that accommodates
the subsystem ID and subsystem vendor ID PCI configuration registers stipulated in the PCI local
bus specifications. The register contains the ID of the add-in board that SH7751 Series is installed
on its subsystem (bits 31 to 16) as well as the subsystem vendor ID (bits 15 to 0).
All bits can be written to from the PP bus.
The PCICONF11 register is not initialized at a reset. Always initialize this register while the
CFINIT bit (bit 0) of the PCICR register is cleared.
Bits 31 to 16—SSID15 to 0: Specifies the subsystem ID.
Bits 15 to 0—SVID15 to 0: Specifies the PCI subsystem vendor ID.
