This register will always return 0,- however it will not return the value
until there are no outstanding write requests between MCU and AON
Note: Writing to this register prior to reading will force a wait until
next SCLK_LF edge. This is recommended for syncing read
registers from AON when waking up from sleep Failure to do so may
result in reading AON values from prior to going to sleep
