PRODUCTION DATA.
The MSP430FR697x(1) and MSP430FR692x(1) MCUs have one active mode and seven software selectable low-power modes of operation (see Table 6-1). An interrupt event can wake up the device from a low-power mode (LPM0 to 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.
