based on characterization data for that particular oscillator type under standard operating conditions with the
device executing code. Exceeding these specified limits may result in an unstable oscillator operation and/or
higher than expected current consumption. All devices are tested to operate at “min.” values with an external
clock applied to the OSC1/CLKIN pin. When an external clock input is used, the “Max.” cycle time limit is
“DC” (no clock) for all devices.
