Over-drive switching characteristics
When the over-drive mode switches from enabled to disabled or disabled to enabled, the
system clock is stalled during the internal voltage set-up.
The over-drive switching characteristics are given in Table 23. They are subject to general
operating conditions for T_A.

Supply current characteristics
The current consumption is a function of several parameters and factors such as the
operating voltage, ambient temperature, I/O pin loading, device software configuration,
operating frequencies, I/O pin switching rate, program location in memory and executed
binary code.
The current consumption is measured as described in Figure 25.
All the run-mode current consumption measurements given in this section are performed
with a reduced code that gives a consumption equivalent to CoreMark^® code.
