Hi guys,
I'm currently working with the UART on the LPC1200.
In the documentation an interrupt can be triggered if a character isn't received between 3.5 and 4.5 characters time to help flush the rx buffer.
From the transmitting side, I wish to use this to create a clear frame-break. If I disable transmission and re-enable, would there typically be a break of at least 3.5 to 4.5 characters or would I have to use a timer to ensure that I've waited long enough before my next transmission?
Many thanks for any help.
