between the duration of the bus minus the Twake, as illustrated below (Trx_dom = Tbus_dom - Twake)
MC33889D in Normal mode
WAKE
Example: A dominant duration at the bus level of 5
bits of 8us each results in a 40us bus dominant.
This results in a 24µs (40µs-16µs) dominant level at
Rx of MC33889D (while the CAN of the MC33889D
is in TermVbat).
