    Hi,

    I have scoured the Microchip datasheet for this device, and although it includes a section on the UART, it is not specific as to the pins of the DIP that the CTS and RTS etc are assigned to. I have looked very carefully at the pin - out of this device, and it doesn't seem to allocate them on this either.
    So i'm wondering if anyone has knowledge of this microcontroller, and if so, where are the UART pins!?

    thank you in advance

    regards

    RB

    IIRC, they are defined in software. There must be a section in the datasheet explaining how to assign the physical pins to the UART.

    yes, i understand that that is how to assign any function to pins in software, but in the pin diagram of the device, there is no indication of what pin the UART is assigned to, in terms of connecting a serial communications chip to the pic(eg, rs232 - MAX233). it must be hidden or written in invisible ink, because it really looks like it is not there!!yet, the datasheet confirms that there is a UART on-board..

    Read section 11 in the data sheet. Then find table 11-1, 11-2. These tables will tell you how to configure which pin used.
