s32k144 uart flow control

[ainwood]

Hello,

I'm working with the S32k144 development board, and I would like to use lpuart1 for communication. Since the messages are large, I need full hardware flow control support. Does anyone know how to enable hardware flow control support on lpuart1?

Hello Andrew,

Hardware flow control support for the request to send (RTS) and clear to send (CTS) signals.

The corresponding pins should be configured by pin mux as LPUART RTS/CTS.

The alternatives for each pin you can find in the pinout in the S32K144_IO_Signal _Description_Input_Multiplexing.xlsx 

For the configuration of RTS or CTS look at the chapter 51.3.1.11 LPUART Modem IrDA Register (MODIR)

Related chapter 51.4.2.2 Hardware flow control

I hope it helps you.

Best regards,

Diana
