GPIOs that are not implemented will not have the corresponding bits implemented in
this register.

QRT_EN—R/W: This bit enables Quick Resume Technology
0 = QRT Disabled
1 = QRT Enabled
When this bit is 0, the R/W bits of QRT Control Registers (QRT_CNT1, EL_CNT2)
scratchpad with no effect on hardware functions. Also, WO bits have no effect on
hardware functions.
BIOS software is expected to set this bit after booting. Default value for this bit is 0.
GPIO15 Route — R/W. See bits 1:0 for description.
GPIO2 Route — R/W. See bits 1:0 for description.
GPIO1 Route — R/W. See bits 1:0 for description.
GPIO0 Route — R/W. GPIO[15:0] can be routed to cause an SMI or SCI when the
GPIO[n]_STS bit is set. If the GPIO0 is not set to an input, this field has no effect.
If the system is in an S1–S5 state and if the GPE0_EN bit is also set, then the GPIO can
cause a Wake event, even if the GPIO is NOT routed to cause an SMI# or SCI.
00 = No effect.
01 = SMI# (if corresponding ALT_GPI_SMI_EN bit is also set)
10 = SCI (if corresponding GPE0_EN bit is also set)
11 = Reserved
