Instruction cycle period (T
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 OSC1 pin. When an external clock input is used, the ‘max’ cycle
time limit is ‘DC’ (no clock) for all devices.
