1. The current consumption of the brownout module is already included in the I_CC current consumption data.
The voltage level V_{(B_IT−)} + V_{hys(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.
