| By default in DM8806, the energy efficient mode is enabled. |
| It had been observed that the network randomly fails when |
| this mode is on. Thus, this symbol is by default disabled. |

| help |
| This functionality prevents the host SMI bus to be interferered by the |
| noise on board-level. During write procedure, the written value in |
| register will be applied until the correct checksum is written. In read |
| procedure, the hardware calculated checksum is compared with the software |
| calculated one to detect correctness of received data. |

| help |
| The numbers of SMI bus transmission repetition in case if CRC checksum |
| fails during read or write. After this numbers of repetition, the reading |
| message is dropped and will not be passed to the system. In write |
| procedure, the written value in register will be applied until the correct |
| checksum is written to the PHY register. |
