NOTE: The time stamp is metered between frame- or DC-interrupts and signal changes on the input
in µs. The value of the time stamp becomes 0xFFFF, when no signal change takes place
between two frame- or DC-interrupts.
In frame-synchronous mode: The time from the last frame-interrupt to the status change of the input is
stored in the time stamp and sent in the following frame to the EtherCAT master.
