PRODUCTION DATA.
The MSP430FR263x and MSP430FR253x MCUs have one active mode and several software-selectable low-power modes of operation (see Table 6-1). An interrupt event can wake the MCU from low-power mode (LPM0 or LPM3), service the request, and restore the MCU 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.
