我现在配置修改的地方为:Cmpss1Regs.COMPDACCTL.bit.SELREF = 1;

我需要cmpss比较器的DAC基准用到VDAC,不是默认的VDDA,
我现在配置修改的地方为:Cmpss1Regs.COMPDACCTL.bit.SELREF = 1;
Reference options for the CMPSS DAC are only VDDA (internal) and VDAC (external).
关于VDAC,请参考技术手册Table 12-2. Analog Signal Descriptions
有一些硬件上的要求
不好意思,再次打扰,我尝试打开了DAC模块,外部基准电压VDAC给定2.5V,发现CMPSS的DAC参考VDAC还是无效,还是按照VDDA做基准。请问有没有这块测试通过的配置发我参考一下,下面是我debug时寄存器配置截图,帮忙看看还需要配置哪一块
抱歉,我目前没有找出您没有设置的地方。建议您在英文E2E询问一下相关BU,谢谢
