7. I/O Address Space
I/O address space has control registers in the LAN controller and the LAN card control register; in some cases,
it has ID numbers. The MB86967 supports both the independent I/O addressing mode, and overlapping I/O
addressing mode. Index 0 of the 32 I/O indexes is used to address the independent I/O, and index 31 is used
to address the overlapping I/O. One index has 32 bytes of address space. In the independent I/O addressing
mode, the I/O address pins A4 to A0 are used.
When using the overlapping I/O addressing mode in the ISA and EISA buses, I/O address space is allocated
to any one of the 31 indexes. The system can select any I/O base address by writing different indexes to bits 0
to 5 of the card configuration option register. In this mode, all I/O address pins A0 to A10 are used.
If 32 bytes of I/O address space are allocated to the control registers in the LAN controller, the LAN card control
register, and ID numbers are as follows:
The configuration indexes and I/O base addresses to be assigned are as follows:
Base Address
+0 to F
+10
+12, 14, 16, 18, 1A, 1C, 1E
Register
Control registers in LAN controller
LAN card control register
For setting ID numbers (only read value valid)
A read value that is not used as the ID number is undefined.
Reserved (The read value is undefined and writing is invalid.)
