| 47 | 1) PCIe core working in clientmode |
| 48 | 2) PCIe Gen 2 clientmode core |

| 50 | In general PCIe (Gen 2) clientmode core is required on PCIe |
| 51 | hosted buses. It's responsible for initialization and basic |

| 81 | Some cheap devices have serial flash connected to the ChipCommon |
| 82 | instead of independent SPI controller. It requires using a separated |
