使用芯片：MSPM0G1507
目的：DAC输出指定信号，ADC根据定时器采样数据通过串口发出来
基于定时器触发dma进行adc采样，第一次debug运行都正常，脱离调试也正常，但是在调试中rest芯片，DMA输出数组值全为0，硬件脱离调试重新启动，DMA输出值也全为0，系统主时钟80M
与此同时DAC+DMA输出永远正常，部分时候会出现systick中断不触发的情况
具体配置如下：
syscfg:
/**

* via the GUI or CLI. Run CLI with '--help' for additional information on how to override these arguments.
* @cliArgs --device "MSPM0G150X" --part "Default" --package "LQFP-48(PT)" --product "mspm0_sdk@2.02.00.05"

运行效果：
正常：
不正常（调试界面点复位或者硬件上reset引脚给一次低电平脉冲）：
ccs和keil同样现象
