NOTE: All inputs are tied to 0 V or VCC. Outputs do not source or sink any current. The current consumption in LPM2, LPM3 and LPM4 are
measured with active Basic Timer1 (ACLK selected) and LCD Module (f(LCD)=1024 Hz, 4 MUX).
current consumption of active mode versus system frequency
IAM = IAM[1 MHz] × fsystem [MHz]
current consumption of active mode versus supply voltage
IAM = IAM[3 V] + 200 μA/V × (VCC3 V)
