I am using MC9S12 for my project. My project is 1 master and more than 10 salve. There is no problem that data can send and receive for 1 master and 1 salve.  One of the salve is hang if two salve send data same time, but master is still working normally. Every time I have to do reset for the salve. Is this problem because  MCU bit rate is 20kbit/s?
