55 / 226 page  2017-2018 Microchip Technology Inc. DS00002419D-page 55 KSZ9563R 4.9.3.1 Standard MIIM Registers (Direct) Standard registers provide direct read/write access to a 32-register address space, as defined in Clause 22 of the IEEE 802.3 Specification. Within this address space, the first 16 registers (Registers 0h to Fh) are defined according to the IEEE specification, while the remaining 16 registers (Registers 10h to 1Fh) are defined specific to the PHY vendor. The KSZ9563R supports the standard registers listed in Table 4-26 for each PHY port. Each 16-bit MIIM Standard Reg- ister Address maps to two corresponding 8-bit Port N Register Addresses. The register bit map and description are located at the 8-bit Port N Register Addresses. 4.9.3.2 MDIO Manageable Device (MMD) Registers (Indirect) The MIIM interface provides indirect access to a set of MMD registers as defined in Section 5.4, "MDIO Manageable Device (MMD) Registers (Indirect)," on page 193.
