This section describes the three low-power modes:
The STOP instruction places the microcontroller unit (MCU) in its lowest
power consumption mode. In 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. See
