另外当DACCLK GONE, DATACLK GONE, or FIFO冲突时 CLOCK GONE(or alarm_output_gone bit) alarm应该设置为1。
The DACCLK_GONE_ENA, DATACLK_GONE_ENA, and COLLSIONGONE_ENA will disable the output whenever the clocks are missing or FIFO collision occurs. You will need to unmask the appropriate alarm registers per the instruction on the register table
另外,可以试试使能自动输出关闭特性(config2, bit 14 to 12),上电报警相关寄存器Register 5 相关位也请清零
自动输出关闭特性(config2,bit14 to 12)这个试过了 不行啊!
