Power-Up Behavior
Power Sequencing
While starting up and shutting down as well as when switching power modes of the
system it is important to limit the current load steps. A typical cause for such load steps
is changing the CPU frequency fCPU. Load steps exceeding the below defined values
may cause a power on reset triggered by the supply monitor.
Note: These parameters are not subject to production test, but verified by design and/or
characterization.
