GPIO1 Pin Wakeup Interrupt Enable
Write 1 to any bit to enable the corresponding pin on the 32-bit GPIO port to
generate an interrupt to wakeup the device from any low power mode to
ACTIVE mode.
A wakeup occurs on any low-to-high or high-to-low transition on the
corresponding pin.
Note: To enable the device to wakeup from a low power mode on a GPIO pin
transition, first set the “GPIO Wakeup enable” register bit
GCR_PMR.gpiowken = 1.

Analog Input Comparator 3 Wakeup Status Flag
This bit is set when the comparator inputs detect an event. Write 1 to clear.
Note: If the corresponding bit PWRSEQ_LPPWEN in register is set, the event
generates an interrupt to wakeup the device from a low power mode.

Analog Input Comparator 2 Wakeup Status Flag
This bit is set when the comparator inputs detect an event. Write 1 to clear.
Note: If the corresponding bit in PWRSEQ_LPPWEN register is set, the event
generates an interrupt to wakeup the device from a low power mode.
