Problem with multiprocessor communication on MKE02P64M40

[anto]

Hi, I am using  mke02P64M40 to create a RS485 application. I would like to use 9-bit multiprocessor communication. When I config the uart0 and try to set the RWU pin into register C2 to put the uart0 in stand by mode, it seems that it is not configured but always remains at 0 (normal mode). You can help me.

Hi Stella,

    I think you can't set the RWU in register C2, it should be already cleared by the hardware condition.

I didn't connect the RX and TX pin, then control the RWU in the UART0 register, you can see the RWU is set:

More details, you can check the reference manual, chapter 31.4.3.2 Receiver wake-up operation.

Wish it helps you!

Have a great day,
Kerry
