Instruction cycle period (T
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 OSCI/CLKI pin. When an external clock input is used, the “Max.” cycle time
limit is “DC” (no clock) for all devices.
Measurements are taken in EC mode. The CLKO signal is measured on the OSCO pin. CLKO is low for the
Q1-Q2 period (1/2 T
