DMA Controller
The DMA controller allows movement of data from one memory address to another without CPU intervention.
Using the DMA controller can increase the throughput of peripheral modules. The DMA controller reduces
system power consumption by allowing the CPU to remain in sleep mode, without having to awaken to move
data to or from a peripheral.

(1) Reserved DMA triggers may be used by other devices in the family. Reserved DMA triggers will not
cause any DMA trigger event when selected.
(2) Only on CC430F614x and CC430F514x. Reserved on CC430F512x.
Watchdog Timer (WDT_A)
The primary function of the watchdog timer is to perform a controlled system restart after a software problem
occurs. If the selected time interval expires, a system reset is generated. If the watchdog function is not needed
in an application, the timer can be configured as an interval timer and can generate interrupts at selected time
intervals.
