Instruction cycle period (TCY) equals four times the input oscillator time base period for all configurations

except PLL. All specified values are 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/CLKI pin. When an external clock

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