*5) Time between the first optical wake-up pattern and switching into active mode

*6) Time between transmitting last bit and switching into sleep mode

*7) Duration for detection of continuous light

*8) After recognizing High levels on the internal data path at the lock switch input (see block wiring

diagram), the other relevant channel is blocked for this period.
