. Outputs do not source or sink any current.
The current consumption in LPM2, LPM3, and LPM4 are measured with active Basic Timer1 and LCD (ACLK selected).
The current consumption of the SD16 and the SVS module are specified i n their respective sections.
LPMx currents measured with WDT disabled.
The currents are characterized with a KDSDaishinkuDT--38(6pF)crystal.
