Reads from or write to a given location in the PCI configuration space.
| PeiServices | An indirect pointer to the PEI Services Table published by the PEI Foundation. |
| This | Pointer to local data for the interface. |
| Width | The width of the access. Enumerated in bytes. See EFI_PEI_PCI_CFG_PPI_WIDTH above. |
| Address | The physical address of the access. The format of the address is described by EFI_PEI_PCI_CFG_PPI_PCI_ADDRESS. |
| Buffer | A pointer to the buffer of data.. |
| EFI_SUCCESS | The function completed successfully. |
| EFI_DEVICE_ERROR | There was a problem with the transaction. |
| EFI_DEVICE_NOT_READY | The device is not capable of supporting the operation at this time. |

Performs a read-modify-write operation on the contents from a given location in the PCI configuration space.
| PeiServices | An indirect pointer to the PEI Services Table published by the PEI Foundation. |
| This | Pointer to local data for the interface. |
| Width | The width of the access. Enumerated in bytes. Type EFI_PEI_PCI_CFG_PPI_WIDTH is defined in Read(). |
| Address | The physical address of the access. |
| SetBits | Points to value to bitwise-OR with the read configuration value. The size of the value is determined by Width. |
| ClearBits | Points to the value to negate and bitwise-AND with the read configuration value. The size of the value is determined by Width. |
| EFI_SUCCESS | The function completed successfully. |
| EFI_DEVICE_ERROR | There was a problem with the transaction. |
