The monitoring of the events on the active inputs continue even during transmission.

The settings associated with this mode of operation are:
• Period of transmission of the frame (register 301)
• The configuration of the different digital inputs (registers 320 to 323)
• The thresholds to be reached before sending the frame (registers 324 to 327)

* Waiting* period (or debounce time): minimum time for taking into account a change of state. For example if this period is 10ms, all pulses
(opening or closing) whose duration is less than 10ms will not be taken into account. This technique prevents rebound on a change of state.
In this example the product is in event mode, the frame 0x40 will be sent if an event (opening or closing) is detected on channel 1 or if 10
closings are detected on channel 2 or if 150 openings occurred on channel 4.
IMPORTANT NOTE: If an event is detected on channel 1, the device will wait during 1 second to check if an other event is simultaneously
detected on an other channel to send it in the same frame.
IMPORTANT NOTE: For each 0x40 frame sent (for an event or periodically) the counters are set to 0 for all the channels.
