PME_EN2
DESCRIPTION
PME Wake Enable Register 2
(Type)
0x0D
This register is used to enable individual LPC47M182
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.
Default = 0x00
