Table 4: Recommended operating conditions
The on-chip power-on reset circuitry may not function properly for rise times
longer than the specified maximum.
A step in supply voltage of 300 mV or more, with rise time of 300 ms or less,
within the valid supply range, may result in a system reset.
An instable supply voltage may significantly decrease the radio performance
and stability.
