NAME
PME_EN1
DESCRIPTION
PME Wake Enable Register 1
0A
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[0] Reserved (Note 7)
Bit[1] RI2
Bit[2] RI1
Bit[3] KBD
Bit[4] MOUSE
Bit[5] SPEKEY (Wake on specific key)
Bit[6] FAN_TACH1
Bit[7] FAN_TACH2
The PME Wake Enable register is not affected by Vcc
POR, SOFT RESET or HARD RESET.
PME Wake Enable Register 2
PME_EN2
0B
This register is used to enable individual LPC47M14x
PME wake sources onto the nIO_PME wake bus.
Default = 0x00

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.
