Tool/software:

Does CC3230SF only have 4 UART lines? My Cellular modem supports 7 UART lines. Please see the picture attached. How can I connect the extra 3 UART lines?

    Hi,

    CC32xx supports UART with RTS and CTS hardware flow (that means pins RX, TX, RTS, CTS). If you want to control other pins you need to control them by yourself (e.g. via GPIO), because CC32xx does not have direct hardware support for this.
