CardBus Function Event Present State (CB_FPS0) Register
L
All bits in this register are reset to zero.
15
INTM
Interrupt / Wakeup Mask.
Enables assertion of
INTA
and
PME//CSTSCHG
when in Card-
Bus mode (
CBUS
= low). Has no effect upon
INTA
or
PME/CSTSCHG
when not in CardBus mode.
In CardBus mode:
INTA
is asserted when:
CB_FEM0:INTM=1
and
CB_FE0:INTR=1
.
CSTSCHG
is asserted high when:
CB_FEM0:INTRM=1
and
CB_FEM0:WKUP=1
and
CB_FEM0:GWKM=1
and
CB_FE0:GWKE=1.
This bit is cleared by power-on reset and
PCI
RST
. It is not affected by
SYSRST
or Soft Reset.
