ZHCSF32E February 2016 – December 2019 MSP430FR2310 , MSP430FR2311
PRODUCTION DATA.
The MSP430 has one active mode and several software-selectable low-power modes of operation (see Table 6-1). An interrupt event can wake up the device from low-power mode (LPM0, LPM3, or LPM4), service the request, and restore back to the low-power mode on return from the interrupt program. Low-power modes LPM3.5 and LPM4.5 disable the core supply to minimize power consumption.
