NOTE 1: The signal applied to the USART0 receive signal/terminal (URXD0) should meet the timing requirements of t(τ) to ensure that the URXS
flip-flop is set. The URXS flip-flop is set with negative pulses meeting the minimum-timing condition of t(τ). The operating conditions to
set the flag must be met independently from this timing constraint. The deglitch circuitry is active only on negative transitions on the
URXD0 line.

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 ≤ 1.8 V.
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.
