The SAFE mode request has the next highest priority after reset which can be generated by software via
the ME_MCTL register from all software running modes including DRUN, RUN0â¦3, and TEST or by
the MC_RGM after the detection of system hardware failures, which may occur in any mode.
25.4.3.2 Target Mode Configuration Loading
On completion of the Target Mode Request, the target mode configuration from the
ME_<target mode>_MC register is loaded to start the resources (voltage sources, clock sources, flashes,
pads, etc.) control process.
An overview of resource control possibilities for each mode is shown in Table 25-16. A âïâ indicates that
a given resource is configurable for a given mode.
