s CONTROL REGISTERS IN LAN CONTROLLER

These control registers are used in all modes (PC card mode, ISA bus mode, and general-purpose bus mode).

The I/O address space between the base and 0 to F addresses has 32 control registers in the LAN controller

for two address-extended bits (RBS1 and RBS0). The two address-extended bits (RBS1 and RBS0) are at bits

3 and 2 of the control register DLCR7 in the LAN controller (base address +7).

Notes:1. At reset, the LAN controller defaults to the 8-bit system interface. However, in the PC card mode, the

8-bit or 16-bit interface is set by bit 5 (IOIS8) of CCR1 at switching from the IC memory interface to the

I/O card interface according to the CCR setting condition.

2. The PC card mode does not support DMA.
