operating modes
The MSP430 has one active mode and five software selectable low-power modes of operation. An interrupt
event can wake up the device from any of the five low-power modes, service the request and restore back to
the low-power mode on return from the interrupt program.
The following six operating modes can be configured by software:
D
Active mode AM;
