DALI collision detected on the backward channel: during the transfer of
a DALI telegram, a collision with the send data of another DALI slave
was detected. The bit SB.2 is reset with the next edge of the bit SB.0,
unless another DALI collision has occurred.

DALI collision detected on the forward channel: during the transfer of a
DALI telegram, a collision with the send data of another DALI master
was detected. The bit SB.1 is reset with the next edge of the bit SB.0,
unless another DALI collision has occurred.
SB.0 Toggle An edge of SB.0 is the acknowledgement for the end of the telegram cycle
initiated with the toggle bit of the control byte (
CB.0 [ } 44] ). The telegram was sent
via the DALI/DSI bus. In DALI mode, the collision bit (SB.1) provides information
about any collisions that may have occurred.
