Register Map
The IEEE 802.3 Specification provides a 32 register address space for the PHY. Registers 0 thru 15 are standard PHY
registers, defined per the specification. Registers 16 thru 31 are vendor specific registers.
The KSZ9021GQ uses the IEEE provided register space for IEEE Defined Registers and Vendor Specific Registers, and
uses the following registers to access Extended Registers:
Register 11 (Bh) for Extended Register – Control
Register 12 (Ch) for Extended Register – Data Write
Register 13 (Dh) for Extended Register – Data Read
Examples:
Extended Register Read
// Read from Operation Mode Strap Status Register
1. Write register 11 (Bh) with 0103h
// Set register 259 (103h) for read
2. Read register 13 (Dh)
// Read register value
Extended Register Write
// Write to Operation Mode Strap Override Register
1. Write register 11 (Bh) with 8102h
// Set register 258 (102h) for write
2. Write register 12 (Ch) with 0010h
// Write 0010h value to register to set NAND Tree mode
