Hum, Im wondering what happens with something like that:
OperationRegion (C0EE, EmbeddedControl, 0x00, 0xFF)
Field (C0EE, ByteAcc, NoLock, Preserve)
{
Offset (0x80),
Offset (0x81),
, 4,
C0EF, 4,
, 1,
C0F0, 1,
^^^^
C0F1, 1,
, 1,
[...]
}
[...]
Method (_REG, 2, NotSerialized)
{
If (LEqual (Arg0, 0x03))
{
Store (Arg1, C0ED)
If (Arg1)
{
C11C (0x07, 0xFF)
Store (C11D (), Local0)
C11E (Local0, 0x81)
And (C0EC, 0x01, C0F0)
^^^^
And (ShiftRight (C0EC, 0x01), 0x01, C0F2)
}
}
}
The C0F0 is actually a inside the EC space handler, but you have
to call _REG with the second argument (Arg1) as 1 when initiliazing
the space handler before accessing C0F0.
