Watchdog Timer (WDT_A) (Link to User's Guide)
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.
DMA Controller (Link to User's Guide)
The DMA controller allows movement of data from one memory address to another without CPU intervention. For
example, the DMA controller can be used to move data from the ADC10_A conversion memory to RAM. 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.
