NOTES: 1. Timer_B is clocked by f(DCOCLK) = 1 MHz. All inputs are tied to 0 V or to V
CC
. Outputs do not source or sink any current.
2. Timer_B is clocked by f(ACLK) = 32,768 Hz. All inputs are tied to 0 V or to V
CC
. Outputs do not source or sink any current. The current
consumption in LPM2 and LPM3 are measured with ACLK selected.
