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 pin. When an external clock input is used, the “max” cycle time limit is “DC” (no
clock) for all devices.
