K32W CTS/RTS

Because Uart coce of the original SDK only has TX/RX, neither will add CTS/RTS.
Does UART need to add CTS/RTS?

Hello,

The usage of the CTS and RTS are mostly used in application level and is up to the customers if they use it or not.

In this case the flash programmer can work without CTS and RTS, you can check more information about this in the Production Flash Programmer Guide.

Now your reply is enough, can you let me know more information.
I can't find it. It is mentioned in the Production Flash Programmer Guide that CTS/RTS is not needed

Hello,

It is good that this is clear now, do you mean that you can't find the document ? If that is the information you can't locate, is already attached in the internal case.

Hope this helps.

Hello !

Could you please help me with the reference on where you are seeing that for the ISP programming you need CTS and RTS ?

If you check the User Manual of the device you can find in the chapter 38.4 Physical Interface

The ISP protocol is implemented on USART 0, using DIO9 for RX and DIO8 for TX. The baud rate is 115200 with formatting of 8 bits per character, no parity bit and 1 stop bit.

Hi Estephania,

You mentioned before that you saw CTS/RTS, so I asked what you saw there?

If there is no further information, just forget this.

I meant more details about the flash programmer usage.

Hope that helped you.

Hi Estephania,

Thank you for your support.
We will continue to read the documents, and we will ask you if we have other questions that we do not understand in the future.
