(1) The current consumption of the brownout module is already included in the ICC current consumption data. The voltage level V(B_IT–) + Vhys(B_IT–) is ≤ 1.8 V.
(2) During power up, the CPU begins code execution following a period of t
d(BOR) after V
CC = V
(B_IT–) + V
hys(B_IT–). The default FLL+ settings must not be changed until V
CC ≥ V
CC(min), where V
CC(min) is the minimum supply voltage for the desired operating frequency. See the
MSP430x4xx Family User's Guide (
SLAU056) for more information on the brownout/SVS circuit.
