7.3.31 FLAG ATTRIBUTES REGISTER (FLAG_ATTR)
This register is supported only by LAN9500A/LAN9500Ai.
Address:
0B0h
Size:
LAN950x
32 bits
This register sets the values of elements of the Configuration Flags and PME flags when no EEPROM is present and
customized operation, using Descriptor RAM images, is to occur. This register does not contain Configuration Flag ele-
ments that are components of other registers. Those elements will be programmed by the driver software directly prior
to initiating customized operation via Descriptor RAM.
Note 1: This register only affects system operation when an EEPROM is not present and the EEPROM Emulation
Enable (EEM) bit indicates Descriptor RAM and the Attributes Registers are to be used for descriptor pro-
cessing.
2: Writing to this register when an EEPROM is present is prohibited and will result in untoward operation and
unexpected results.
3: This register is protected by Reset Protection (RST_PROTECT).
