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 CLKO signal is measured on the OSC2 pin. CLKO is
low for the Q1-Q2 period (1/2 T
