DC Electrical Characteristics 888CF:
Note 11: Rate of voltage change must be less then 0.5 V/ms.
Note 12: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.
Note 13: 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
