NOTES:
1. The signal applied to the USART receive signal/terminal (URXD) 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 URXD line.

NOTES:
1. This parameter defines the minimum supply voltage VCC when the data in the program memory RAM remains unchanged. No
program execution should happen during this supply voltage condition.

NOTES:
1. The current consumption of the brown-out module is already included in the ICC current consumption data.
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 DCO settings must not be changed until VCC ≥ VCC(min), where VCC(min) is the minimum supply voltage for the
desired operating frequency. See the MSP430x1xx Family User’s Guide for more information on the brownout circuit.
