4.6 Address Filter Registers
4.6.1 Logical Address Filter (hash table)
(Read/Write, Address: PacketPage base + 0150h)
The CS8900A hashing decoder circuitry compares its output with one bit of the Logical Address Filter Register. If
the decoder output and the Logical Address Filter bit match, the frame passes the hash filter and the Hashed bit
(Register 4, RxEvent, Bit 9) is set. See Section 5.2.10 on page 87.
Reset value is: 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000
4.6.2 Individual Address (IEEE address)
(Read/Write, Address: PacketPage base + 0158h)
The unique, IEEE 48-bit Individual Address (IA) begins at 0158h. The first bit of the IA (Bit IA[00]) must be "0". See
Section 5.2.10 on page 87.
The value of this register must be loaded from external storage, for example, from the EEPROM. See Section 3.3
on page 19. If the CS8900A is not able to load the IA from the EEPROM, then after a reset this register is undefined,
and the driver must write an address to this register.
