With each edge change of the toggle bit, the KL6811 sends a DALI or DSI
telegram. The telegrams can be transmitted at intervals of 25 ms, i.e. within 100
ms the KL6811 can send a maximum of 4 telegrams.
Depending on the content (with or without return channel), the duration of a DALI
telegram cycle is between 25 and 43.34 ms. The end of a DALI telegram cycle is
indicated by an edge of the toggle bit in the status byte (SB.0 [} 44]).
