This section describes the three low-power modes:
The STOP instruction places the microcontroller unit (MCU) in its lowest
power consumption mode. In the stop mode, the internal oscillator is
turned off, halting all internal processing including timer, serial
communications interface (SCI), and master mode serial peripheral
interface (SPI) operation.
