关于DAC38J84输出固定数据的问题

Other Parts Discussed in Thread: DAC38J84

我使用DAC38J84的config47和config48输出一个固定的数据时没有输出,我的配置如下:

 sifdac_ena =1;When asserted the DAC output is set to the value in register sifdac. 

sifdc This is the value that is sent to the digital blocks when register sifdac_ena is asserted.设置为0x7fff;其他配置按照初始化流程配置。不知道这样能否输出一个固定数据的电平?
