The MCU contains two software instructions, WAIT and STOP, to
reduce power consumption when processing is not required. Both
instructions suspend operation until a reset or interrupt occurs while
retaining register and RAM contents. The wait condition suspends
processing, reducing power consumption to an intermediate level. The
stop condition turns off all on-chip clocks as well and reduces power
consumption to an absolute minimum.
