ULP
The MSP430 supports this sleep/wake/sleep profile quite well, by providing a variety of low-power
modes (LPM). The following chart is an example of the LPM's found on various MSP430 devices,
showing which resources are powered down by LP mode. It also broadly indicates what it takes
to wake up from a given LPM. (In general, LPM0 and LPM3 are very popular modes.)
Almost as important is the 430's ability to wake up quickly from a sleep mode as is demonstrated
on the next slide. The DCO (digitally controlled oscillator) is one of the on-chip, high-performance
clocks available to the MSP430. The graphic is powerful statement, showing how quickly the
clocks and system can be up-and-running after receiving an interrupt.
