部件号：MSPM0G1507 工具/软件：
你（们）好
目前、我正在使用 采用 MSP430 微控制器的 PMP7647_RevC 设计解决方案。 我计划迁移到 MSPM0G1507、
对于所面临的问题、我需要一些帮助。
ADC 相关：
我们没有使用 DMA。 使用 ADC 中断读取所有 ADC 值。 我们希望与您联系了解有关 ADC 相关设置的信息。
如何 在每次读取后将 DL_ADC12_getMemResult (ADC12_0_INST、DL_ADC12_MEM_IDX_0) 设置为零？
如何使用 PWM 触发 ADC？ （我们希望在 PWM/2 处获取 ADC 读数）
在 MS430 中、由 SW PMMCTL0 |=PMMSWBOR 进行欠压复位。 MSPM0 中是否有同等产品？
此致、
Yogesh
