Using BREAK DETEC with UART, LPC936 - abaehne - Nov 24 2:54:03 2008
Hello,
I would like to use the BREAK DETEC Flag to handle the following data
in the BREAK DETECT ISR. In the NXP User Manual for the LPC936 I'read
that the UART goes in an Idle Mode when an BREAK DETECT occurs and the
UART wakes up when a stop bit is read. This could means for me that the
first Byte, which comes direkly after the BREAK DETECT, is not in the
SBUF because of the Idle Mode of the UART at this time.
Does anybody know how I could force the UART to stay awake after a
BREAK DETECT?
Regards
Andi

simple solution would be to connect the pin to the INT0.

Re: Using BREAK DETEC with UART, LPC936 - abaehne - Nov 24 4:21:51 2008
Hello,
thanks for answer. I don't understand the advantage to work with INT0.
Could you please explain it to me?
Thanks.
