UARTx_C2 send break?

danielchai — Thu, 05 Jun 2014 21:07:45 GMT

Hi All,

For K60, the UARTx_C2 SBK bit is used to send break.

Does it mean when I set the SBK bit, it will send break continuously until I clear the SBK bit?

Or it means after SBK is set, it only send 10, 11, 12, 13 or 14 logic 0s no matter if SBK is cleared or not?

Thank you.

If you set the SBK bit the UART will continuously send break characeters until you remove the bit. Then it will complete sending the break character that it was in the process of sending before returning to the idle line state.
