5.2 Device Group Registers
Each input is continuously monitored to check whether a proper differential signal is being applied. When a non-differential signal is detected longer than the delay time, this input is considered faulty. The delay register is used to specify this delay time and can be set to a value between 0 and 255. The delay will be 100ns times the value of this register. It is recommended to use delay times longer than 500ns to prevent normal transitions of the input signals from triggering the fault detection mechanism.
