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.
Measurements are taken in EC or ERC modes. The CLKOUT signal is measured on the OSC2 pin.
CLKOUT is low for the Q1-Q2 period (1/2 T
