NOTES:
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 ≤ 1.8V.
2. During power up, the CPU begins code execution following a period of td(BOR) after VCC = V(B_IT) + Vhys(B_IT). The default FLL+
settings must not be changed until VCC ≥ VCC(min), where VCC(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.
