DC Electrical Characteristics
Note 2: Rate of voltage change must be less then 0.5 V/ms.
Note 3: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.
Note 4: The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations. Test conditions: All inputs tied to V
outputs and set high. The D port set to zero. The A/D is disabled. V
Note 5: The user must guarantee that D2 pin does not source more than 10 ma during RESET. If D2 sources more than 10 mA during reset, the device will go into
programming mode.
AC Electrical Characteristics
Note 6: The output propagation delay is referenced to end of the instruction cycle where the output change occurs.
