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_CC, L and G0–G5 configured as
outputs and set high. The D port set to zero. The A/D is disabled. V_REF is tied to AGND (effectively shorting the Reference resistor). The clock monitor is disabled.
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.
