Note 11: Supply and IDLE currents are measured with CKI driven with a square wave Oscillator, CKO driven 180˚ out of phase with CKI, inputs connected to V
and outputs driven low but not connected to a load.
Note 12: The HALT mode will stop CKI from oscillating. Measurement of I
G0, and G2–G5 programmed as low outputs and not driving a load; all D outputs programmed low and not driving a load; all inputs tied to V
