msp430FR2xx/4xx的DMA问题

Other Parts Discussed in Thread: MSP430FR2311

因为项目需要,想找一款具有FRAM的430单片机,希望具有ADC和DAC模块。最后在“MSP430FR4xx and MSP430FR2xx Family User's Guide’” 中了解到,MSP430FR2311内部具有一个"SAC (smart analog combo)" 可以使用12 bits的一个DAC。

但19.2.4.1节的如下描述

The DAC module is a 12-bit voltage-output digital-to-analog converter. The DAC can be configured in 12-bit mode and supports DMA data transfer,很是奇怪。

因为430FR2XX和4XX 好像没有任何一个型号具有DMA模块;且MSPWARE中也没有提供这两个系统的任何DMA例程。
