. Outputs do not source or sink any current. The current consumption is measured with active Basic
Timer1 and LCD (ACLK selected). The current consumption of the Comparator_A and the SVS module are specified in the respective
sections.
(2) Current consumption for brownout included.
(3) The LPM3 currents are characterized with a KDS Daishinku DT−38 (6 pF) crystal.
