In summary, the information presented in this module has defined low power, discussed the MSP430 low power modes, and how the interrupts relate to them. Additional topics included the clock system and how it affects the low power modes along with discussions relating to the device-specific clocking options and calibrating the DCO and the FLL. Finally, the principles for ultra-low power applications with respect to the MSP430 were discussed and are summarized in this slide. More detailed information can be found on the MSP430 clocking system in the device family users guides.
