6.2 Address Map
The “Access” column in the QSM address map below indicates which registers are accessible only at
the supervisor privilege level and which can be assigned to either the supervisor or user privilege level,
according to the value of the SUPV bit in the QSMCR.
Y = M111, where M is the logic state of the MM bit in the SIMCR.
