192 / 232 page  KSZ9567R DS00002329D-page 192 2017-2019 Microchip Technology Inc. 5.3.1.6 ALU Table Entry 3 Register 5.3.1.7 ALU Table Entry 4 Register 5.3.2 STATIC ADDRESS TABLE The Static Address Table is one of three tables used for MAC address lookup. It can hold up to 16 static address entries, thereby minimizing the number of static entries that may need to be programmed into the Address Lookup Table, which is used primarily for dynamic entries. In response to a destination address (DA) lookup, all tables are searched to make a packet forwarding decision. Entries in this table are programmed by the host processor, and are never aged. A static DA lookup result (in either this table or the Address Lookup Table) takes precedence over the dynamic DA lookup result. The Static Address Table has 16 entries and is accessed indirectly. The Static Address and Reserved Multicast Table Control Register is used for indexing and read/write control. The following registers are used for the data fields: • Static Address Table Entry 1 Register • Static Address Table Entry 2 Register • Static Address Table Entry 3 Register • Static Address Table Entry 4 Register 5.3.2.1 Static Address Table Write Operation 1. Write the content of the table entry to the Static Address Table Entry 1 Register, Static Address Table Entry 2 Register, Static Address Table Entry 3 Register, and Static Address Table Entry 4 Register. 2. Write to the Static Address and Reserved Multicast Table Control Register. a) Write the TABLE_INDEX field with the 4-bit index value. b) Set the TABLE_SELECT bit to 0 to select the Static Address Table. c) Set the ACTION bit to 0 to indicate a write operation. d) Set the START_FINISH bit to 1 to initiate the operation. 3. When the operation is complete, the START_FINISH bit will be cleared automatically. 5.3.2.2 Static Address Table Read Operation 1. Write to the Static Address and Reserved Multicast Table Control Register. a) Write the TABLE_INDEX field with the 4-bit index value. b) Set the TABLE_SELECT bit to 0 to select the Static Address Table. c) Set the ACTION bit to 1 to indicate a read operation. Address: 0x0428 - 0x042B Size: 32 bits Bits Description Type Default 31:23 RESERVED RO 0x000 22:16 FID VLAN group ID for matching R/W 000_0000 15:0 MAC Address [47:32] R/W 0x0000 Address: 0x042C - 0x042F Size: 32 bits Bits Description Type Default 31:0 MAC Address [31:0] R/W 0x00000000 |
