Description
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
Writing a 1 to this bit forces a shutdown request to be registered and
all I/O values to be latched - in the PAD ring, possibly enabling I/O
wakeup. Writing 0 will cancel a registered shutdown request and
open th I/O latches residing in the PAD ring.
A registered shutdown request takes effect the next time power
down conditions exists. At this time, the will not enter Powerdown
mode, but instead it will turn off all internal powersupplies, effectively
putting the device into Shutdown mode.
