[En-Nut-Discussion] Break Error

[Michael Jones]

Hello Uwe,

The break condition is issued when the signal is held low longer than die
total frame length. The Frame error on the other side indicates that e.g.
the parity bit is invalid. The break state is often used in old protocols to
act as a 257th character mostly as begin-of-frame or out of band data
indicator. 

Cu,
Michael

Subject: [En-Nut-Discussion] Break Error

Hello Ole,

can you explain what a "BREAK ERROR" in serial handling is? I looked at the
STM32 reference manual, and someting like "BREAKERROR" is not mentioned
there. Probably a line kept low for longer than one frame should produce a
BREAKERROR? Where does it differ from a framing error?

Bye
