When SD modulator clock fails or goes missing for 256 continuous system clock cycles, clock fail detection sub-module in the input control unit of SD modulator detects the failure and generates an interrupt to CPU. This mechanism can be used to detect missing modulator clock faults or any faults in digital I/O connecting modulator clock.
