I/O BASE
UNLOCK
Read/Write
0
The I/O base address is not changed even after an I/O-read
operation to address X12H (BMPR18).
1
An I/O-read operation to address X12H (BMPR18) increments
the values of the I/O base address select signals (IOSEL0 to
IOSEL2), causing a change in the I/O base address (This is
valid only in the jumperless ISA bus mode).
6
Not used
Read/Write
The read value of this bit is always 0.
Writing 1 is prohibited. Always write 0 to this bit.
5
LINK TEST
ENA
Read/Write
0
The link test on the 10BASE-T transceiver is enabled.
1
The link test on the 10BASE-T transceiver is disabled.
4 to 2
Not used
Read/Write
The read values of these bits is always 0.
Writing 1 is prohibited. Always write 0 to these bits at writing.
1 and 0 DMA BRST

Read/Write
The DMA transfer cycle count is set by one bus request
(These bits are invalid in the PC card mode).
