Description
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
Requests the AUX domain bus to be disconnected from the MCU
domain bus. The request has no effect when
AON_WUC:AUX_CTL.AUX_FORCE_ON is set.
The disconnection status can be monitored through MCUBUSSTAT.
Note however that this register cannot be read by the system CPU
while disconnected.
It is recommended that this bit is set and remains set after initial
power-up, and that the system CPU uses
AON_WUC:AUX_CTL.AUX_FORCE_ON to connect/disconnect the
bus.
