I need a clock signal for my hardware that occurs in the middle of each uart tx bit. But I don't want the synchronous mode behavior where receives are based on transmits. I want receives to start when start bits are received on the uart rx pin, which may be in the middle of a transmit byte.
I don't see how to set this up since there is a control bit for the tx clock but I don't see a separate control bit for sync mode.
If this isn't possible then I will set up a timer pwm with a period equal to a bit width and reset the counter when I start a transmission. This will be dependent on clearing the counter at precisely the right time in sw, which may be hard to do.
Any ideas?
