NOTES: 1. Timer_B is clocked by f
(DCOCLK)

(DCO)
= 1 MHz. All inputs are tied to 0 V or to V
CC
. Outputs do not source or sink any current.
2. All inputs are tied to 0 V or to V
CC
. Outputs do not source or sink any current.
3. All inputs are tied to 0 V or to V
CC
. Outputs do not source or sink any current. The current consumption in LPM3 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. The LPM3 currents are characterized with a KDS Daishinku DT−38 (6 pF) crystal and OSCCAPx=1h.
