Description of Functional Blocks
Asynchronous Awake (LT-S, NT, Int. NT mode)
The transceiver is in power down mode (deactivated state) and MODE1.CFS=1
(TR_CONF0.LDD is don’t care in this case). Due to any signal on the line the level detect
circuit will asynchronously pull the DU line on IOM-2 to “0” which is deactivated again
after 2 ms if the oscillator is fully operational. If the oscillator is just starting up in
operational mode, the 2 ms duration is extended correspondingly.
