FPGA signal, by assign USB_WR = I2c_config_done Cmos_href Usb_trigger; it is known that USB allows data to be written when pd5=1.• When Frame_cnt%2==0, write FIFO in 15FPS;• When the condition frame_cnt%2==0 is met, the Pd5=1, which allows write FIFO, is not satisfied, pd5=0, the write FIFO is forbidden.• Resets the FIFO 2 each time the write FIFO is blocked. So that the FIFO 2 data is empty so that there is no FIFO full state. This prevents data l
