DESCRIPTION
PME Wake Status Register 5
This register indicates the state of the individual PME wake

on VTR POR

(R/W)
sources, independent of the individual source enables or
the PME_En bit.
If the wake source has asserted a wake event, the
associated PME Wake Status bit will be a “1”.

The PME Wake Status register is not affected by Vcc
POR, SOFT RESET or HARD RESET.
Writing a “1” to Bit[7:0] will clear it. Writing a “0” to any bit
in PME Wake Status Register has no effect.

PME_EN1
PME Wake Enable Register 1
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.
