Power Well:
This register is symmetrical to the General Purpose Event 0 Status Register. All the bits
in this register should be cleared to 0 based on a Power Button Override or processor
Thermal Trip event. The resume well bits are all cleared by RSMRST#. The RTC sell bits
are cleared by RTCRST#.

GPIn_EN — R/W. These bits enable the corresponding GPI[n]_STS bits being set to
cause a SCI, and/or wake event. These bits are cleared by RSMRST#.
NOTE: Mapping is as follows: bit 31 corresponds to GPIO15... and bit 16

0 = Disable.
1 = Enables the setting of the PME_STS to generate a wake event and/or an SCI.
QRT_SCI_EN — R/W. In Desktop Mode this bit enables the QRT_SCI_STS signal to
cause an SCI (depending on the SCI_EN bit) when it is asserted
BATLOW_EN — R/W.

USB3_STS bit is set anytime USB UHCI controller #3 signals a wake event.
Break events are handled via the USB interrupt.
