1. Guaranteed by design, not tested in production.
2. Guaranteed by design, not tested in production. This parameter is the latency between the time when pin
NPOR is set to 1 by the application and the time when the VREFINTRDYF status bit is set to 1 by the
hardware.

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
