在ccs中一开始DEBUG时registers中UCA0IFG为什么值为0X02?
你好！
如果你是将USCIA配置为SPI用，UCA0IFG初始化就是0x02.
因为UCA0IFG的bit1是UCTXIFG，当发送缓冲区为空是，该位置1.
详见
MSP430x5xx/MSP430x6xx Family User's Guide
chapter 36 36 Enhanced Universal Serial Communication Interface (eUSCI) – SPI Mode
希望能够帮到你！
再请教一个问题，这边的registers中UCA0IFG的值在DEBUG以后会不会随着接受中断的产生不断的改变呢？或者说能不能具体的讲讲CCS的各模块如何调试
