AIC-6915 Ethernet LAN Controller Programmer’s Manual
Address Filtering Registers
Perfect Address Memory Register
Type: R/W
Internal Registers Subgroup: Address Filtering Memory Access
Byte Address: 6000h - 6FFFh
Table 7-108 starts at byte address 6000h from the internal registers base address, offset
56000h from the AIC-6915’s base address. No bits have reset values, so all bits
corresponding to enabled functions must be written. Note that word 3 is not used, and
that data is transferred only on the lower 16-bits of words 2, 1, and 0.
