Wake-up Detector
event is detected. Only the first wake-up event is indicated in the wake-up source bit. In case the TLE9221SX
detects a local and a remote wake-up event simultaneously, the wake-up source bit output indicates the remote
wake-up event.
The SIR is reset either after a complete read-out of the SIR (see Chapter 6.2.3) or when the TLE9221SX enters
into BD_Normal mode. The wake-up flag is reset if both bits, the local wake-up bit and the remote wake-up bit are
reset.
The wake-up flag and the wake-up source bit are indicated at the ERRN output pin of the Host Interface (see
Table 9).
