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 ADC12_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.

(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 devices with peripheral module DAC12_A. Reserved on devices without DAC.
Universal Serial Communication Interface (USCI) (Links to User's Guide: UART Mode, SPI Mode,
I2C Mode)
The USCI modules are used for serial data communication. The USCI module supports synchronous
communication protocols such as SPI (3 or 4 pin) and I
2
C, and asynchronous communication protocols such as
UART, enhanced UART with automatic baudrate detection, and IrDA. Each USCI module contains two portions,
A and B.
