(1) This value represents the time from the wakeup event to the first active edge of MCLK. The wakeup time depends on the performance
mode of the low-side supervisor (SVS_L) and low side monitor (SVM_L). Fastest wakeup times are possible with SVS_Land SVM_L in full
performance mode or disabled when operating in AM, LPM0, and LPM1. Various options are available for SVS_Land SVM_L while
operating in LPM2, LPM3, and LPM4. See the Power Management Module and Supply Voltage Supervisor chapter in the MSP430x5xx
and MSP430x6xx Family User's Guide (SLAU208).
(2) This value represents the time from the wakeup event to the first active edge of MCLK. The wakeup time depends on the performance
mode of the low-side supervisor (SVS_L) and low side monitor (SVM_L). In this case, the SVS_Land SVM_L are in normal mode (low current)
mode when operating in AM, LPM0, and LPM1. Various options are available for SVS_Land SVM_L while operating in LPM2, LPM3, and
LPM4. See the Power Management Module and Supply Voltage Supervisor chapter in the MSP430x5xx and MSP430x6xx Family User's
Guide (SLAU208).
(3) This value represents the time from the wakeup event to the reset vector execution.
