NOTES: 1. Timer_A is clocked by f
(DCOCLK)
= f
(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. The LPM3 currents are characterized with a Micro Crystal CC4V−T1A (9pF) crystal and OSCCAPx=01h.
4. Current for brownout included.
