PME Wake Enable Register 4
This register is used to enable individual LPC47M10x PME
wake sources onto the nIO_PME wake bus.
When the PME Wake Enable register bit for a wake source
is active (“1”), if the source asserts a wake event so that
the associated status bit is “1” and the PME_En bit is “1”,
the source will assert the nIO_PME signal.
When the PME Wake Enable register bit for a wake source
is inactive (“0”), the PME Wake Status register will indicate
the state of the wake source but will not assert the
nIO_PME signal.

The PME Wake Enable register is not affected by Vcc
POR, SOFT RESET or HARD RESET.
PME Wake Enable Register 5
This register is used to enable individual LPC47M10x PME
wake sources onto the nIO_PME wake bus.
When the PME Wake Enable register bit for a wake source
is active (“1”), if the source asserts a wake event so that
the associated status bit is “1” and the PME_En bit is “1”,
the source will assert the nIO_PME signal.
When the PME Wake Enable register bit for a wake source
is inactive (“0”), the PME Wake Status register will indicate
the state of the wake source but will not assert the
nIO_PME signal.

The PME Wake Enable register is not affected by Vcc

Reserved – reads return 0
SMI Status Register 1
This register is used to read the status of the SMI inputs.
The following bits must be cleared at their source.
Bit[0] Reserved
Bit[1] PINT. The parallel port interrupt defaults to ‘1’ when
the parallel port activate bit is cleared. When the parallel
port is activated, PINT follows the nACK input.
Bit[2] U2INT
Bit[3] U1INT
Bit[4] FINT
Bit[5] MPU-401 INT
Bit[6] Reserved
Bit[7] Reserved (Note 7)
