DM9102A

Single Chip Fast Ethernet NIC Controller

and bit 6 are set

RO

Address/Data Stepping (0 for No Stepping)

RW

Parity Error Response Enable/Disable

Setting this bit will enable the DM9102A to assert PERR# on the detection

of a data parity error and to assert SERR# for reporting address parity

error

RO

VGA Palette Snooping (0 for No Support)

RO

Memory Write and Invalid (0 for No Implementation)

The DM9102A only generates memory write cycle

RO

Special Cycles (0 for No Implementation)

RW

Master Device Capability Enable/Disable

When this bit is set, DM9102A has the ability of master mode operation

RW

Memory Space Access Enable/Disable

This bit controls the ability of memory space access. The memory access

includes memory mapped I/O access and Boot ROM access. As the

system boots up, this bit will be enabled by BIOS for Boot ROM memory

access. While in normal operation, using memory mapped I/O access,

this bit should be set by driver before memory access cycles

RW

I/O Space Access Enable/Disable

This bit controls the ability of I/O space access. It will be set by BIOS after

power on
