NAME
PME_EN3
DESCRIPTION
PME Wake Status Register 3
0C
This register is used to enable individual LPC47M14x
PME wake sources onto the nIO_PME wake bus.
Default = 0x00
on VTR POR
(R/W)
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.

Bit[3] DEVINT_EN (Enable bit for group SMI signal for
PME)

The PME Wake Enable register is not affected by Vcc
POR, SOFT RESET or HARD RESET.
