Notes:
Note: Interrupt events enabled by these bits are be routed to the PWR_MNG Bit 0 in the ISR_1 register.
SMSC DS – USB97C100
Any transition from high to low, or low to high on the associated input sets these bits. These bits are cleared
each time this register is read.
Since this register will report any status change, when devices are to be powered down while monitored, the
appropriate bits must be masked until the device is armed correctly.
