Hi all, I have a project to develop a micro-controlling system based on motorola`s 68hc11A1.So far I`ve managed to complete everything except for the interface. I am to connect the mcu with a pc through USB FT232. On the USB`s pdf i saw that i have to connect the usb`s TxD to the MCU`s RxD and the usb`s RxD to the MCU`s TxD, I aslo need to control the transfer rate meaning connecting RTS and CTS, And here is my question i red that hc11 does not have RTS and CTS signals so I am to use 2 general purpose I/O for to generate them but I`m not sure wich registers/flags should I be checking for them is TDRE an TC flags from SCSR register or ...?
