1. Shortest sampling time can be determined in the application by multiple iterations.
2. Guaranteed by design, not tested in production.
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
measurement
All Run-mode current consumption measurements given in this section are performed with a
reduced code that gives a consumption equivalent to Dhrystone 2.1 code.
