AP6212 is just the node attributes printed by the kernel, in fact the driver is compatible with AP6212 and AP6335. … WebTXD[1:0], and RX_ER. REF_CLK is sourced by the MAC or an external source. REF_CLK is an input to the DP83848 and may be sourced by the MAC or from an external source such as a clock distribution device. The REF_CLK frequency shall be 50 MHz ± 50 ppm with a duty cycle between 35% and 65% inclusive. The DP83848 uses REF_CLK as the …

WebApr 12, 2024 · 2. In verilog, when you are instantiating a module, that means you are adding extra hardware to the board. This hardware must be added before simulation starts (i.e. at compile time). Here, you can not add/remove hardware at each clock pulse. Once instantiated, the module is executed/checked for each timestamp of simulation, till the end. on the summary
