49 / 100 page  MII REGISTER MAP SUMMARY Table 17 contains the MII register map summary for each port of the BCM5228. The register addresses are specified in hex form, and the name of register bits have been abbreviated. When writing to any register, preserve existing values of the reserved bits by completing a “Read/Modify Write.” Ignore reserved bits when reading registers. Never write to an undefined register. The reset values of the registers are shown in the INIT column. Some of these values could be different depending on how the device is configured and also depending on the device revision value.
