This surely can't be right? If TI was set when starting to transmit, it would surely serve no useful purpose?
For the traditional derivatives TI is set at the stop bit; however, some newer derivatives (seen it, do not remember which) have added a double buffer for the transmit SBUF. Check the datasheet for your derivative. For double buffered derivatives, you can use the TI interrupt and some "keep track" code OR just enable reception and use the RI interrupt. Using the RI interrupt will, of course, remove the advantage of the double buffering. Now, enabling reception is required for multimaster apps, otherwise you have no means for collision detection. Master/slave setups work by collision avoidance. Erik |
