Autobaud Detection is Waiting
Either character ‘a’, ‘A’, ‘t’, or ‘T’ has been
detected.
The autobaud detection unit waits for the
first ‘a’ or ‘A’
Bit is cleared when either FCSDET or
FCCDET is set (‘a’ or ‘A’ detected). Bit can
be also cleared by software. DETWAIT is
set by hardware when ABCON_ABEN is
set.
Note: SCSDET or SCCDET are set when the second character has been recognized.
CON_ABEN is reset, and ABDETIR set, after SCSDET or SCCDET have seen
set.
The baud rate timer reload register BG contains the 13-bit reload value for the baud rate
