BASE ADDRESS REGISTER
READ/WRITE
For Local Bus mode only, this register holds the I/O address decode option chosen for the I/O and ROM
space. It is part of the EEPROM saved setup, and is not usually modified during run-time.

A15 - A13 and A9 - A5 - These bits are compared in Local Bus mode against the I/O address on the bus to
determine the IOBASE for LAN91C96I registers. The 64k I/O space is fully decoded by the LAN91C96I
down to a 16 location space, therefore the unspecified address lines A4, A10, A11 and A12 must be all
zeros.
ROM SIZE - Determines the ROM decode area in Local Bus mode memory space as follows:
00 = ROM disable
01 = 16k: RA14-18 define ROM select.
10 = 32k: RA15-18 define ROM select.
11 = 64k: RA16-18 define ROM select.
RA18-RA14 - These bits are compared in Local Bus mode against the memory address on the bus to
determine if the ROM is being accessed, as a function of the ROM SIZE. ROM accesses are read only
memory accesses defined by MEMRD* going low.
For a full decode of the address space unspecified upper address lines have to be: A19 = "1", A20-A23
lines are not directly decoded, however Local Bus systems will only activate SMEMRD* only when A20-
A23=0.
All bits in this register are loaded from the serial EEPROM in Local Bus Mode only.
The I/O base decode defaults to 300h (namely, the high byte defaults to 18h). ROM SIZE defaults to 01.
ROM decode defaults to CC000 (namely the low byte defaults to 67h).
