Table D-4 is the QSM address map. The column labeled “Access” indicates the privi-
lege level at which the CPU must be operating to access the register. A designation of
“S” indicates that supervisor access is required: a designation of “S/U” indicates that
the register can be programmed to the desired privilege level.
Y = M111, where M is the logic state of the module mapping (MM) bit in the SIMCR.
QSMCR bits enable stop and freeze modes, and determine the arbitration priority of
QSM interrupt requests.
When STOP is set, the QSM enters low-power stop mode. System clock input to the
module is disabled. While STOP is asserted, only QSMCR reads are guaranteed to be
valid, but writes to QSPI RAM or any register are guaranteed valid. STOP is set during
RESET:
