我用FPGA产生24M时钟给DM365做主时钟(MXI1,MXO1不连接),有人这样用过吗??有什么隐患吗??
你好,
DM36x支持外部有源晶振输入时钟,只要FPGA输出的时钟幅度是1.8v并且稳定,我认为可以使用。下面的信息可以在DM365数据手册上找到:
Note: If an external oscillator is to be used, the external oscillator clock signal should be connected to the
MXI1 pin with a 1.8V amplitude. The MXO1 should be left unconnected and the VSS_MX1 signal should
be connected to board ground (Vss).
谢谢你!我也打算这么用!还想请教的问题!!DM365所有的GPIO都可以做外部中断用吗??谢谢!
手册上的这句话是什么意思??“Up to 15 unique GPIO[15:0] interrupts from Bank 0.”
