Product data sheet
6.3.1 Bus wake-up via wake-up pattern
6.3 Remote wake-up
A valid remote wake-up event occurs when a wake-up pattern is received. A wake-up
pattern consists of at least two consecutive wake-up symbols. A wake-up symbol consists
of a DATA_0 phase lasting longer than t
longer than t
t
DATA_1 phases.
The wake-up mechanism of the TJA1082 follows the state transition diagram shown in
