5.4 Miscellaneous Registers

The miscellaneous registers are located at MDIO Manageable Device (MMD) address 0x1F.

Important: RESERVED address space must not be written to except when specifically directed to by Microchip. Failure to heed this warning may result in adverse operation and unexpected results.

Important: When writing to registers containing RESERVED bit fields, use a read-modify-write operation to avoid accidental modifications to RESERVED bit fields. Failure to use a read-modify-write operation may result in adverse operation and unexpected results.
