In addition, if the user doesn’t want Si570 controller to configure Si570 as soon as the FPGA
configuration finishes, users can change settings in Si570_controller.v, shown below.
initial_config initial_config(
.iCLK(iCLK), // system clock 50mhz
.iRST_n(iRST_n), // system reset
.oINITIAL_START(initial_start),
.iINITIAL_ENABLE(1'b1),
);
Changing the setting from ".iINITIAL_ENABLE(1'b1) " to ".iINITIAL_ENABLE(1'b0)" will
disable the initialization function of Si570 Controller.
