PRODUCTION DATA
The devices have one active mode and several software-selectable low-power modes of operation. An interrupt event can wake up the device from low-power mode LPM0 or LPM3, 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.
