CS8900A  
Crystal LAN™ ISA Ethernet Controller  
4.6 Address Filter Registers  
4.6.1 Logical Address Filter (hash table)  
(Read/Write, Address: PacketPage base + 0150h)  
Address 0157h Address 0156h Address 0155h Address 0154h Address 0153h Address 0152h Address 0151h Address 0150h  
Most-signifi-  
cant byte of  
hash filter.  
Least-signifi-  
cant byte of  
hash filter.  
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 5.3 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)  
Address 0015Dh  
Octet 5 of IA  
Address 0015Ch  
Address 0015Bh  
Address 0015Ah  
Address 0159h  
Address 00158h  
Octet 0 of IA  
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 5.3 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.
