Revision A3
Df4/DFEMR Function Event Mask Register
This register gives software the ability to control what events in the function cause the Status Changed
interrupts or the host system Wakeup. This register controls the assertion of the signals INTAB and
CSTSCHG in a CardBus system.

R/W
INTR_
EN
Interrupt Enable
Setting 1 enables the INTR in the function Event register to
generate interrupt on the INTAB pin.
14
Sticky bit,
R/W
WKUP_
EN
Wake-up Enable
Setting 1, enables the GWAKE bit in the register Df0/DFER
to generate the Wakeup event on the CSTSCHG line if the
GWAKE_En field is set together. When this bit reset to 0, the
Wakeup function is disable.
This bit defaults to 0 if PMEB generation from D3
cold
is not
supported. If PMEB generation from D3
cold
is supported, then
this bit is sticky and must be explicitly cleared by the
operating system each time it is initially loaded.

4
Sticky bit,
R/W
GWAKE_
EN
General Wake-up Enable
Setting 1, enables the GWAKE bit in the register Df0/DFER
to generate the Wakeup event on the CSTSCHG line if the
WKUP field is also set .
When reset to 0, the Wakeup function is disable.
This bit defaults to 0 if PMEB generation from D3
cold
is not
supported. If PMEB generation from D3
cold
is supported, then
this bit is sticky and must be explicitly cleared by the
operating system each time it is initially loaded.
Note: When W89C841F is configured into CardBus system, setting or
clearing PME_En bit in register Fe0/FPMR1[8] will also setting or
clearing GWAKE_EN & WKUP_EN bits at the same time. Bits
GWAKE_EN & WKUP_EN are allowed to be reset after setting
PME_En bit.
