关于msp430g2553在grace下设置8mhz时钟出错的问题



我在使用grace配置时钟时发现,当设定doc为8mhz,为smclk提供时钟。

总是提示我有两个错误

一个是Selected CPU frequency has insufficient VCC. Requires a minimum of 2.7V to operate. 

一个是ti.catalog.msp430.peripherals.clock.BCSplus.Instance#0 MCLKHz: Selected CPU frequency has insufficient VCC. Requires a minimum of 2.7V to operate.

我查了下是说至少vcc需要2.7v供电才行。

为什么会出现这种问题啊?需要怎么解决?

另外,我这里是想做一个grace的练习。手动敲的话,没有问题。希望可以用grace解决。

先谢谢大家了
