Registers 118 to 120
Registers 118 to 120 are User Defined Registers (UDRs). These are general purpose read/write registers that can be
used to pass user defined control and status information between the KSZ8873 and the external processor.
Register 118 (0x76): User Defined Register 1
Register 119 (0x77): User Defined Register 2
Register 120 (0x78): User Defined Register 3
Registers 121 to 131
Registers 121 to 131 provide read and write access to the static MAC address table, VLAN table, dynamic MAC address
table, and MIB counters.
Register 121 (0x79): Indirect Access Control 0
Register 122 (0x7A): Indirect Access Control 1
Note: A write to register 122 triggers the read/write command. Read or write access is determined by register 121 bit 4.
Register 123 (0x7B): Indirect Data Register 8
Register 124 (0x7C): Indirect Data Register 7
