UART in my code transmits a character, yet on the oscilloscope I find it gave me another signal

If you try to use 9600 bps rate with 32768 Hz clock, it is not possible, the actual baud rate will be faster, 10923 bps.

That is 13% faster than requested 9600 bps, and thus out of tolerance requirement for receiver operating at 9600 bps rate.
