Bit Field Type Reset Description

31-1 RESERVED R/W X

Software should not rely on the value of a reserved. Writing any

other value than the reset value may result in undefined behavior.

0 EN R/W X

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.
