Control and Status Registers (CR)
The DM9102A implements 16 control and status registers,
which can be accessed by the host. These CRs are double
long word aligned. All CRs are set to their default values by
hardware or software reset unless otherwise specified. All
Control and Status Registers with their definitions and offset
from IO or memory Base Address are shown below:

Key to Default
In the register description that follows, the default column
takes the form:
<Reset Value>, <Access Type>
Where
<Reset Value>:
1
Bit set to logic one
0
Bit set to logic zero
X
No default value
<Access Type>:
RO = Read only
RW = Read/Write
RW/C = Read/Write and Clear
WO = Write only
Reserved bits are shaded and should be written with 0.
Reserved bits are undefined on read access.
