ABCON for interrupt generation, if required)
Polling interrupt request flag or waiting for the autobaud detection interrupt
12.1.8.2 Serial Frames for Autobaud Detection
The autobaud detection of the ASC is based on the serial reception of a specific two-byte
serial frame. This serial frame is build up by the two ASCII bytes "at" or "AT" ("aT" or "At"
are not allowed). Both byte combinations can be detected in five types of asynchronous
frames. Figure 89 and Figure 90 show the serial frames which are detected at least.
