21 / 101 page ![]() MSP430F533x www.ti.com SLAS721B – AUGUST 2010 – REVISED AUGUST 2012 DMA Controller 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. Table 14.

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) The USCI modules are used for serial data communication. The USCI module supports synchronous communication protocols such as SPI (3 or 4 pin) and I2C, and asynchronous communication protocols such as UART, enhanced UART with automatic baudrate detection, and IrDA. Each USCI module contains two portions, A and B. Copyright © 2010–2012, Texas Instruments Incorporated 21 |
