当需要拍照时,就会调用clk_prepare_enable来使能图像传感器的时钟,然后才能进行图像采集等操作。 在多时钟域的系统中,clk_prepare_enable也常用于在不同时钟域之间进行切换或同步。一个系统中有高速时钟域和低速时钟域,当数据需要从高速时钟域传输到低速时钟域时,可能需要先通过clk_prepare_enable准备好目标低速时钟域...
电平信号 就楼上信号带- 的 为低电平有效 ！不同的时钟IC 开启信号不同！有的低电平开启 有的高电平开启！

Have I to re-design the logic to support the clock enable pin of each custom instruction that come from the Nios II core??? http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/dry.gif Are there cases in which the Nios II core decides to freeze my logic for...
In the fec_main.c is function phy_reset_after_clk_enable() which should fix problem, but it do not change physical pin status to phy's RST pin (from SNVS_TAMPER9). I have measured pins with oscilloscope and RST pin change status at startup and seguence, but clock will disable aft...
