Register
Description:
PCI configuration port address/command/byte enables register. Provides address, command, and data
byte enables for CSR-initiated accesses of the PCI Controller PCI configuration registers in the PCI Core.
A write to this register that sets the CRP_CMD[16] bit to a 0 (read) will initiate a read of the PCI
Controller PCI configuration register addressed by CRP_AD[7:2]. The resultant read data will be written
to the pci_crp_rdata register.
Access: See below.
