MCUBUSSTAT is shown in
MCU Bus Status
Indicates the connection state of the AUX domain and MCU domain buses.
Note that this register cannot be read from the MCU domain while disconnected, and is therefore only
useful for the AUX_SCE.

Description
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
Indicates whether the AUX domain and MCU domain buses are
currently disconnected (1) or connected (0).
Acknowledges reception of the bus disconnection request, by
matching the value of MCUBUSCTL.DISCONNECT_REQ.
Note that if AON_WUC:AUXCTL.AUX_FORCE_ON = 1 a reconnect
to the MCU domain bus will be made regardless of the state of
MCUBUSCTL.DISCONNECT_REQ
