SysClk=Frequency of System Clock (Hz)/1000. For example, if the system clock is 20 MHz, this value
would be 20000.
Unit: sys-ticks in 1 ms (MSB first)
Note: Wrong configuration will make IMAOS’s timer work improperly.
Timer of entering failure alarm state. When a defect persists for a period set by this timer, the
IDT82V2608 will enter failure alarm state.
Unit: 1 s
Timer of exiting failure alarm state. If a defect no longer exists for a period set by this timer, the
IDT82V2608 will exit failure alarm state.
Unit: 1 s
Reserved. Write 0 to this field.
Alpha value is the number of consecutive incorrect HEC fields for the Rx cell synchronization state
machine to exit sync state.
Delta value is the number of consecutive correct HEC fields for the Rx cell synchronization state machine
to enter sync state.
